Hart Scientific Model 9140 Field Metrology Wells
|
Whether you need to calibrate 4 to 20mA transmitters or a simple thermostatic switch, a Hart Scientific Model 9140 field metrology well is the right tool for the job. With three models covering the range of –25°C to 660°C, this family of Hart Scientific Model 9140 field metrology wells calibrates a wide range of sensor types. The optional process version provides a built-in two-channel thermometer readout that measures PRTs, RTDs, thermocouples, and 4 to 20mA transmitters which includes the 24 V loop supply to power the transmitter.
Additionally, Hart Scientific Model 9140 field metrology wells allow for two types of automated thermostatic switch test procedures - auto or manual setup. Auto setup requires the entry of only the nominal switch temperature. With this entry, the Hart Scientific Model 9140 field metrology well will run a 3-cycle calibration procedure and provide final results for the dead band temperature via the display. If you need to customize the ramp rate or run additional cycles, the manual setup allows you to program and run the procedure exactly how you would like.
