DTG42 Sanitary Digital Temperature Gauge

Brand: Intempco Controls, Inc

The DTG41 Series Digital Temperature Gauge is a complete solution for most sanitary temperature monitoring and temperature indicating applications. 

This gauge features a bright and large 4-digit red LED display, optional Analog 4-20 mA output, optional switch output, and an optional RTD output. 

Based on Intempco’s patented MIST technology, the DTG is designed for optimum accuracy and performance. 

The DTG is an ideal replacement for bi-metal, liquid bulb and gas thermometers. DTG can be factory calibrated to customer specified temperature range, in units of °C or °F. 

But the unique feature of the DTG is that it is field re-programmable. Process temperature or alarm setpoint change? No problem! 

Simply use DTG-PKIT PC interface module and re-range your DTG without the need to re-calibrate and without loss of accuracy. 

DTG is much more accurate than an RTD and a separate indictor/transmitter. When the DTG is re-scaled to a different temperature range, the calibrated default values are not lost. 

This gauge can be customer re-calibrated by performing one-point or two-point calibration using known temperature standards. 

This is where the DTG leaves the competition behind. Indicating temperature range, current output, switch set point, switching hysterises, switch logic, damping and other features are all programmable. 

The user can also set password and code protections. This feature ensures a high degree of temper resistance.
