2-WIRE TRANSMITTER FOR LOAD CELLS AND PRESSURE TRANSDUCERS
PXTX-507

2-WIRE TRANSMITTER FOR LOAD CELLS AND PRESSURE TRANSDUCERS
Provides Transducer Excitation for one ≥350 Ω Bridge
Selectable Input Ranges
Works with 350 Ohm to 5 kΩ Strain Sensors
Zero and Span Adjustability
Converts mV/V sensor output to 4 to 20 mA Loop Signal
Rugged, Industrial Housing



1 Year Warranty


This is a 2-wire, 4-20 mA Current Transmitter that accepts signals from 350, 500, 1K, 2.5K and 5K ohm bridges and provides the amplification and common-mode rejection necessary to control the current drawn from a 8 to 40 Vdc source to produce the 4-20 mA output signal. The transmitter is designed for 0.5 to 4.0 mV/V bridge sensitivities. The transmitter does not provide isolation between its input and the 4-20 mA output. It has two internal reference voltages for powering the bridge. The 1.24 volt reference is used with 1K ohm and lower resistance bridges. The 2.5 volt reference is used with 2.5K and 5K ohm bridges.
