Order no.: PCE-LOC 20

GTIN (EAN): 4250348718167

Description

PCE-LOC 20 Process Calibrator
For Simulation and Measurement of Current and Voltage / Li-Ion battery / Continuity tester / Ramp function / Data logger

The process calibrator PCE-LOC 20 can be used to directly simulate process currents in current loop, mV and mA. This allows the process calibrator to be used to set process displays, data loggers, paperless recorders, etc. Thanks to the galvanically isolated connections, this process calibrator can simultaneously serve as a source and as a measuring device. Here, it does not matter whether currents are measured and voltages are simulated, since the functions work completely independently of each other.

The process calibrator PCE-LOC 20 has a high accuracy of 0.02% of the measured value in all operating modes. The process calibrator is powered by a rechargeable battery that can be charged via a USB power adapter. The memory can also be read out by the process calibrator via this interface. For ease of operation, the LCD contributes from the process calibrator.

In addition to the direct specification of the simulated parameters, the process calibrator has a ramp mode that allows the parameters to be changed incrementally and automatically over a defined period of time. The process calibrator PCE-LOC 20 can also specify the scaled process value. This means, for example, that a temperature in °C / °F is specified directly and the process calibrator simulates the analog process value in mA.
