Model 175 Push Button Zero Differential Pressure Transducer
As a pressure transducer supplier, Alpha instruments Inc specialized in the development and manufacture of low pressure transducer, including the environmental chamber pressure sensor.
Product Description
The model 175 Series high accuracy pressure transducers/transmitters arelow pressure transducers and low pressure transmitters. Each unit features a push-activated ZERO function and an associated 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 a flame retardant plastic top cover and a stainless steel bottom plate for ruggedness.This series of ultra low pressure transducerare sold well, including the surface mount pressure transducer.
The pressure ranges from 0.1″WC to 100″WC, unidirectional or bidirectional. The output can be 3-wire 0 to 5V, 0 to 10V, or 2-wire 4 to 20 mA, fully protected against short circuiting and incorrect wiring. All units are temperature compensated. 0.6%, 0.4% and 0.25% accuracy are available.
The patented stainless steel diaphragm sensor provides good corrosion resistance, excellent repeatability and long term stability.
