The Altronic DPYH-1379U temperature gauge is a solid-state instrument which provides a continuous temperature readout with an alarm/shutdown capability at user-adjusted temperature limits. Using industry standard thermocouple probes, the device is user-selectable for either type J or K sensors and for degrees C. or F. readout. Power is from an industrial C.D. ignition system or 12-24 Vdc. The solid-state output limit switches can be used with Altronic annunciators/controllers or other specified devices (such as solenoids, or conventional relays) operated from DC current. The display indicates the channel and temperature; a momentary push of the CHANNEL button changes the readout to the next channel. The setpoint limit values can be read on the display and adjusted until the display readout matches the desired temperature. The 4-1/2” round, weather-resistant case fits an industry-standard panel cutout allowing easy replacement of analogue/mechanical devices.
