Wired digital temperature transmitter SM39TCRD

Introduction

The SM39TCRD wired temperature sensor has a stainless-steel probe and an aluminum explosion-proof junction box, and is widely used for temperature measurement in thermal engineering, power, food, pharmaceutical, pressure vessel, petrochemical and other process industries, as well as in large equipment such as ovens, plastic and fiber machines, and refrigeration units.

Characteristics：

• Imported Pt100 element for fast response;
•  customizable shape;
•  0–200 °C range (made-to-order);
•  requires pipe drilling/welding and pre-installing a 1/4″ threaded thermowell or boss;
•  terminal block inside junction box for quick wiring;
•  explosion-proof design fully compliant with GB 3836.1-2000, GB 3836.2-2000, and GB 3836.4-2000.
