For the Pallister: • From the menu system select menu option: E: 1 and press ENTER. • Ensure the sensor is in a zero-gas environment. • Press ENTER to zero the sensor, ‘– – – –‘will be displayed to confirm the sensor zero has been performed. • Press MENU to close the menu system. 2. For The LVDT: Using Clisp Studio (using a Micrometer as a reference) Readings from an LVDT and from either the precision gauge blocks (method A) Or the micrometer fixture (method B) are compared to determine the linearity and repeatability of the LVDT. The Results are used to determine the acceptability of the LVDT for laboratory use (Refer to Figure one) Page | 2 - zero Suppression vs. Temperature: ±0.005% (Vz)3/°C Page | 3 Figure 1 UNITED STATES DEPARTMENT OF THE INTERIOR BUREAU OF RECLAMATION Procedure for calibrating linear differential transformers https://www.usbr.gov/tsc/techreferences/mands/rockmanual/tan_earthmanualUSBR/USBR1008.pdf 3. For the Thermocouple: The simplest way to calibrate a temperature sensor is to check how it reads the temperature of two physical constants: the temperature at which ice melts and the boiling point of water (although the latter should be corrected for atmospheric pressure). While quick and inexpensive, one weakness of this method is that it is typically not a NIST traceable calibration.

The sensor body equipped with a connector has an outer diameter of only 8 mm and therefore is especially well suitable for the integration in dimensionally restricted structures. Typical application fields are displacement and extension measurements on ► Machines ► Servo systems ► Motor vehicles ► Test benches ► Production plants Description The cylindrical case made of stainless steel, houses a differential transformer (LVDT). It consists of a primary and two secondary coils with axially moveable core. A displacement of this core changes the magnetic induction of the coils. The IN- LINE carrier frequency amplifier converts the displacement into a direct proportional electrical DC voltage. The transducer is constructed as a probe at which within the measuring range a spring pushes the probe tip towards the measuring object. Bellows protect the mechanical guidance of the probe tip against pollution and splash water. The IN-LINE amplifier is integrated in the connector cable and adjusted specifically to the sensor. Both components form a unit while they can be separated for mounting purposes (miniature plug connection at the transducer). The use of not harmonized components may lead to increased measurement errors. For the IN-LINE amplifier version the sensor body is galvanically isolated from the excitation and from the measuring signal. Lateral forces decrease the durability.

The sensor is supplied as a matched pair of pellistor elements mounted on a single header and protected by a metal mesh enclosure and can. Note: The value R1 is arbitrary, since the function of R1 is to balance the bridge. 1KΩ is suggested. The sensor detects and measures the presence of flammable gases and vapours in air, in the range 0- 100% of the Lower Explosive Limit (LEL) of the gas or vapour being measured. Designed as a lower cost alternative to the twin-header NP-13 device, the NP-13S is especially suitable for use in applications such as cap-lamp mounted gas detectors. Temperature Range: -20°C to +70°C Temperature Drift: (-20°C to +70°C) Zero: < +/- 2%LEL Humidity: 0-100%RH, non-condensing Humidity Response: +/- 2%LEL L inearity: Effectively Linear to 60%LEL The NP-13S exhibits excellent long term zero and sensitivity stability and its resistance to catalytic poisons is also excellent when compared to other low power pellistor type gas sensors available. The highly automated manufacturing procedure employed by Nemoto results in a repeatable reliable sensor which, unlike similar devices, requires no trimming resistor to enable the detector to be matched with a compensator. Test data on drift, poisoning, temperature performance, linearity will be available on the Characterisation Document NP-13CD.doc Nemoto has a policy of continuous development and improvement of its products.

FEATURES Interfaces, amplifies and filters input voltages from a J, K, T, E, R, S, B or N-type thermocouple. Module provides a precision output of either +1 V to +5 V or 0 V to +10 V, linear with input temperature. All 7B47 series modules are mix-and-match and Hot Swappable. APPLICATIONS Industrial signal conditioning Industrial signal isolation Industrial signal filtering PRODUCT OVERVIEW The 7B Series of signal conditioners feature small size, low cost and a wide output voltage range for a variety of applications including process control and factory-floor environments. The single-channel 7B modules accept inputs from a range of transducers and are fully rated over the extended -40oC to +85oC industrial temperature range. All 7B Series modules are rated for a nominal power supply input of +24 VDC; and, for maximum flexibility, they will accept supply voltages in the +14 VDC to +35 VDC range. The input modules, with the exception of the 7B21, provide a high-level output voltage that is factory configured for either the +1 V to +5 V or 0 V to +10 V range. The 7B21 is a unity gain, isolated input module with an input/output range of +10V. Output modules are available that provide either isolated process current or isolated bipolar voltage output. Model 7B39 converts either a +1 V to +5 V input to a 4 to 20 mA output or a 0 V to +10 V input to a 0-20 mA output. The input/output ranges of the 7B39 are factory configured. The 7B22 is a unity gain module that provides an isolated +10V output signal. All modules have a universal pin- out and may be readily hot-swapped under full power without disrupting field wiring. Each module accepts analog transducer signals and transfers them to a process control or factory data collection system without the inherent noise, non-linearity, drift and extraneous voltages which frequently accompany the signals. FUNCTIONAL BLOCK DIAGRAM Figure 1. 7B47 Functional Block Diagram The modules feature a maximum nonlinearity of +0.02% and are factory calibrated to guarantee a maximum accuracy specification of +0.1%. The 7B Series offers up to 1500 V rms continuous common mode voltage isolation and 120 V rms of field wiring input protection. The power supplies necessary to drive each of the individual module’s input circuitry are internally isolated, enabling the 7B Series modules to offer true channel-to-channel isolation of the input signals. The modules directly accept analog signals from thermocouples, RTDs, current loop powered transmitters, and other process control signals. The 7B Series modules amplify, linearize, isolate, protect and convert the transducer output signals to standardized analog inputs for high-level analog I/O subsystems. The 7B Series Subsystem consists of 19-inch rack- compatible hardware (model AC 1363), with universal mounting backplane and a family of plug-in (up to 16 per backplane) input and output signal conditioning modules. Four- , eight-, and sixteen-channel backplanes are available. Each backplane incorporates screw terminals for easy power connections and field wiring, and includes a 25-pin D-type connector for interfacing the high-level single-ended voltage outputs to the user’s equipment. Gold-plated sockets are provided on each channel of the backplane to ensure the reliability of each module’s electrical connection. 7B47 Rev. 0 | Page 2 of 8 GENERAL DESCRIPTION The 7B47 is a single-channel signal conditioning module that interfaces, amplifies and filters input voltages from a J, K, T, E, R, S, B, or N-type thermocouple and provides an isolated and protected precision output of either +1V to +5V or 0 to +10 V, linear with input temperature. High accuracy internal cold junction compensation and a predictable upscale open circuit indication provide a complete signal conditioning solution. To accurately measure low level signals in electrically noisy environments, 1500 V rms of galvanic transformer-based isolation with a common mode rejection (CMR) of 160 of 160 dB @ 50/60 Hz and a normal mode rejection (NMR) of 60 dB @ 50/60 Hz are provided. Rated to operate with a nominal +24 VDC supply, Model 7B47 is mix-and-match and hot-swappable with other 7B Series input modules, so it can be inserted or removed from any socket in the same backplane without disturbing system power. The three input pins of model 7B47 are fully protected up to 120 V rms line voltages. A one-pole 3 Hz filter preconditions the thermocouple signal prior to amplification, provided by a low drift input amplifier. Cold junction compensation (CJC) is implemented using a thermistor temperature sensor embedded under the input screw terminal block on a 7B Series backplane. A voltage reference source acts to offset the thermocouple signal in accordance with the specified lower bound on the input temperature range. A current source provides the upscale open circuit indication. Amplitude modulation is used to implement transformer isolation (1500) V rms input-to-output and power). Isolated front-end circuitry power is supplied by a DC/DC converter. The output section contains a demodulator, linearizer. A two-pole low pass filter (-3 dB @ 3 Hz), a buffer amplifier and a power oscillator. The two-pole output filter and subsequent buffer ensures that a low noise, low impedance (<1Ω) signal is available at the output to drive loads down to 2 kΩ .
