STT17H intelligent temperature transmitter
HART/4 ~ 20mA output, various temperature sensor input
Product Description:
The STT17H intelligent temperature transmitter provides an economical solution for temperature detection applications. The STT17H is more accurate, safe and reliable, and reduces the cost of wiring compared to the directly connected temperature measuring points. The temperature signal output of this temperature transmitter is automatically linearized within the upper and lower limits set by the user. In addition, users can program high - and low-limit alarm points and make them alarm if the sensor fails.
Product features:
HART/4-20mA output
Type B DIN rail or head mount
It can be connected with HART multipoint mode
Thermal resistance, thermocouple, resistance value or millivolt input
Single or dual sensor (difference or average) input
Sensor fault signals comply with NAMUR NE43
It is configured using the STT17C configuration tool and PC or HART field configuration
Electrical isolation
