General Information The PX2670 Series pressure transducers and transmitters sense differential pressure and gage (static) pressure and convert this pressure difference to a proportional high level analog output for both unidirectional and bidirectional pressure ranges. Two versions are offered: the voltage model transducer with 0 to 10 VDC output and the current model transmitter with 4 to 20 mA output. Environmental Conditions The PX2670 Series is designed to be operated and stored in the foll

The Model 267 voltage output is a 3-wire circuit, with three terminals available for wiring (see Figure 1). The -Excitation and -Output are commoned on the circuit (see Figure 2A). The 267 voltage output can operate from either AC (9-30 VAC) or DC (12-40 VDC) excitation. The 267 has a 0-10 VDC output, calibrated at the Factory.

Zero Adjustment - Voltage While monitoring the voltage between the positive output (+OUT) and common (-OUT), and with both ports open to atmosphere, the zero may be adjusted. For unidirectional pressure ranges, turn the zero adjustment screw until a reading of 0.050 VDC is achieved. For bidirectional pressure ranges set to 5 VDC. Zero Adjustment - Current While monitoring the current output with both ports open to atmosphere, the zero may be adjusted. For unidirectional pressure ranges, turn
