TST-03 temperature transmitter is the high performance temperature transmitter that accepts RTD (Pt100, Pt1000), inputs and converts it to a 4 to 20 mA DC or 0 to 5 V DC signal for transmission. Integrative metal housing structrue, local LCD display can be selected. Features 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 environments, Variety of sensor inputs: The type of sensor input is user-selectable from RTD (Pt100, Pt1000)
