The Practical Instrument Electronics (PIE) PIECAL 521B Thermocouple Simulator simulates a dedicated standard thermocouple curve over the entire industrial temperature range. The PIE 521B provides precise temperatures for inputs to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. PIECAL 521B is cold-junction compensated for changes in ambient temperature. The PIE 521/B offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced thermocouple calibrators.

The low cost PIE Model 521B is an "easy as PIE" to use thermocouple source for checkout and calibration of all thermocouple instruments in the field, shop or control room.

Easy to use:With the PIECAL 521B you can check & calibrate all your thermocouple instruments. Connect via a miniature thermocouple jack on the top end of the source. Use your own thermocouple wire connectors or order one of the wire kits for easy operation out of the box.

Take it into the shop, plant or field: Carry it without worry - protect it with an optional rubber boot and rugged, low profile switch. Easy to operate even in the dark areas of the plant with the backlit display.

Calibrate directly in temperature (°C & °F): Stop carrying around a millivolt source and thermocouple tables. The PIE 521B works with the thermocouples you use including types J, K, T, E, R, S, B, N, G, C, D, L (J-DIN), U (T-DIN) and P (Platinel II). Easily set any value quickly to within 0.1° with the adjustable digital potentiometer "DIAL" plus store any three temperatures for instant recall with the EZ-CHECK switch. Or calibrate from -13.000 to +80.000 mV.

Compatible with ALL process instruments: No competitor's calibrator is compatible with as many process instruments! Connect directly to the thermocouple inputs of smart transmitters, PLCs, DCS and multichannel recorders and verify their outputs or displays. Works with older instruments and newer multichannel instruments that switch between input channels.

Evolutionary design:The PIE 521B improves upon other brands by including backlit display with larger digits, rugged switches and a battery compartment for fast battery changes. Add an optional rubber boot with tilt stand for extra protection on the plant floor or in the field.
