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.
The Series TTE is ideally suited for refrigeration, building
automation, commercial hot water heaters and boilers, and
water chillers applications.
