PIECAL's 334 loop calibrator is compatible with recorders, digital indicators, stroke valves, or any instrument with a 4-20 mA input. The calibrator can be used at any access point in a 4-20 milliamp DC loop, and replaces a two-wire transmitter to check loop wiring and receiver.
While measuring the output of loop devices, the 334 can simultaneously output 24 VDC to power the devices in a process loop by using its internal batteries and internal switching power supply. The PIECAL 334 is comparable to Altek's model 334 and 334A calibrators.
