TST Series Temperature Transmitter
The TST temperature transmitter comprises a platinum resistance temperature probe, an advanced temperature conversion module, and a protective housing. Utilizing high-quality platinum resistance as its sensing element, the sensor accurately measures temperature changes. The measured resistance signal undergoes internal amplification, precise non-linear correction, V/I signal conversion, constant current operation, and reverse polarity protection, resulting in a stable, linear electrical signal output corresponding directly to the temperature.
Protected by a durable stainless steel casing, the temperature probe ensures reliable performance in various conditions. The transmitter head features a waterproof aluminum junction box, rail-mounted instrument box, or top-mounted enclosure, offering high sensitivity, exceptional stability, precise measurement accuracy, and extended service life.
- High performance: Micro-processor-based sensing technology ensures long-term accuracy and high reliability.
- High reliability: Dual-compartment housing realizes high resistance capability to harsh environment, Variety of sensor inputs: The type of sensor input is user-selectable from RTD (Pt100, Pt1000).
