Description
Digital pressure gauges provide a back lit display of the pressure, which is useful for dimly lit areas. Some variations or features available include visual indication of a user-set pressure “alarm” (such as the LED display changing from green to red to indicate alarm status). The accuracy for digital pressure gauges tends to be very high, ranging from 1% to ¼% full scale. The connections can be stainless steel or plastic, with or without an isolation diaphragm. The dial sizes fall within the 2½” to 3″ range.
Power options include 9v battery to replaceable lithium battery for up to 3 years of continuous use. You can select the desired pressure units and some models provide a 4-20mA output with two relays.
