Low Pressure Transducer AI175 With LED Indicators
Pressure Medium: Air/Gas
Sensor Type: Differential
Supply Voltage: 5V
Output Signal: Voltage, 4-20 mA
Pressure Range: Under 4” H2O
Kind: Packaged Transducer

Model 175 Series are low-range differential pressure transducers and transmitters. Each unit features a push-activated ZERO function and an ssociated LED lamp indicator. With a convenient pushbutton, the zero calibration can be performed without any additional equipment.

It significantly reduces time and cost for users. The unique bi-color LED indicates if the transducer is at normal operation, over pressure, or in the process of zero calibration. It also reports if the unit is badly damaged.

The enclosure consists of a flame retardant plastic top ocver and a stainless steel bottom plate for ruggedness. The pressure ranges are from 0.1" WC to 100" WC, unidirectional or bidirectional. The output can be 3-wire 0-5V, 0-10V, or 2-wire 4-20 mA, fully protected against short circuiting and incorrect wiring. All units are temperature-protected against short circuiting and incorrect wiring. All units are temperature-compensated. 0.8%, 0.4% and 0.25% accuracy are available. The patented stainless ssteel diaphragm sensor provides good corrosion resistance, excellent repeatability and long-term stability. The AI175 is a great alternative to the Ashcroft CXLdp.
