TTE

Explosion-Proof RTD Temperature Transmitter

User Selectable Ranges, Optional LCD Display

*Shown with optional LCD display

The Series TTE Explosion-Proof RTD Temperature Transmitter is the

ideal product for hazardous temperature measurement applications. The TTE series has seven pre-programmed temperature ranges that are selectable via an internal dip switch. For those applications that need a custom range, the transmitter can be easily configured for any range between -30 to 250°F with a minimum span of 40°F. The span and zero can be quickly adjusted with a simple push button design. The compact housing allows for the transmitter to be mounted in virtually any application.
