Model TX82B is a 1/8 DIN-sized two-wire current-loop indicator that is powered directly by 1-5 mA, 4-20 mA or 10-50 mA process signals, with no need for external power connections. This reduces field wiring costs and provides immunity from most electrical noise encountered in process-control environments. The two-wire electrical hookup is easy via a plug-in screw-clamp connector, which is standard.

Readout of Process Variables
The TX82B provides extensive zero and span adjustment capability for direct readout in percent or in engineering units for process variables such as pressure, flow, temperature, or level. A 0.50 in (12.7 mm) high LCD display provides 3 1/2 active digits for readout to ±1,999, two jumper-selectable dummy right-hand zeros for display to ±19,990 or ±199,900, and five jumper-selectable decimal points. With the dummy zeros, the TX82B can thus be used to display the weight of heavy trucks in pounds or the volume of large tanks in gallons.

Easy to Configure and Calibrate
Both span and zero are fine-tuned with precision 15-turn potentiometers accessible behind the lens. Coarse zero and span steps as well as the dummy right-hand zero are selected by opening the case and changing push-on jumpers.

Intrinsic Safety Certification
FM intrinsic safety certification is standard. Intrinsic safety certification allows the unit to be used in worst-case hazardous environments with no need for explosion-proof housing, provided that an intrinsic safety barrier is used to limit the voltage and current that may be introduced in the hazardous environment. FM certification (USA) is for Class I, II, III, Division 1, Groups A,B,C,D,E,F,G. The FM certification number is 2P1A7.AX (3610:2010)

Built for Industrial Environments
Model TX82B is housed in a splash resistant case and requires a depth of less than 3.9" (100 mm) behind the panel. A splash-proof lens cover which meets NEMA-4 requirements is optional. Electrical connections are via a three-pole male header connector on the circuit board and a mating plug-in socket connector with screw clamps, which accommodate wire sizes of 0.5 to 2.5 mm (26 to 16 AWG). These supplied connectors provide easy and reliable electrical connections and meet UL and IEC-348 safety requirements.
