Room 4 to 20 mAdc Temperature Transmitters with Platinum
Sensors
Model Chart
Specifications
These transmitters use platinum electronic sensors
to control room temperature from a wall location.
The sensed temperature is converted to a rapid
response 4 to 20 mAdc output signal for
microprocessor-based energy management
systems.
Features:
• Two wire 4 to 20 mA current loop.
• Adaptability to TAC System 8000 controllers.
• Class A DIN platinum high accuracy elements
• Low electrical noise transmission.
• Highly accurate current amplifier linearity of ±0.01% of
span.
• Adaptability to energy management systems.
• Short circuit protection.
