Pressure Indicating Transmitter- Series 620
1/16 DIN Housing, Digital Readout, 4 - 20 mA Output
The Series 620 Pressure Indicating Transmitter is a 1/16 DIN instrument for measuring, controlling and indicating positive, negative or differential pressures of air and compatible gases. Pressure measurements are displayed on an easy-to-read 3 ½ digit display and converted to a standard 4-20 mA output signal. Versatile circuit design enables use in 2, 3 or 4-wire current loops.ses.
