Model 175 Push Button Zero Differential Pressure Transducer
Alpha instrumentsis an experienced differential pressure transmitter supplierand differential pressure transducer manufacturer/factory. We are very proud to provide pressure transducers and transmitters for HVAC and other fields. We have low to mid-range pressure sensors available. With our unique product design and production set-up, we strive to meet any customer’s needs.
The model 175 Series high accuracy pressure transducers/transmitters are low-range low pressure transducerand low pressure transmitter. 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 surface mount pressure transduceris 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.
The pressure rangesofultra low pressure sensorfrom 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.
