Wireless digital temperature transmitter SM39TWB

Introduction

SM39TWB wireless temperature transmitter is a high-precision, intelligent temperature measuring instrument developed by our company in accordance with the latest national standards.

It employs a high-accuracy PT100 resistance temperature detector as the sensing element, delivering excellent performance with high accuracy, strong vibration resistance, minimal temperature drift, outstanding stability, and simple operation for precise temperature measurement across a wide range of applications.

Characteristics：

• Industrial temperature measurement, already deployed in major oil and gas fields nationwide and other industrial sectors.
•  Explosion-proof design: flameproof aluminum enclosure with intrinsically safe circuitry.
•  Protection class IP67, fully sealed and waterproof.
• Zigbee communication; can be configured and tested as a coordinator or router in the network.
• 4½-digit LCD shows temperature and battery voltage.
•  LEDs indicate reset, configuration mode, network entry, and data acquisition.
• Adjustable mounting orientation via the supplied swivel or union fitting on the thermowell.
• Adjustable insertion depth: the probe length, and thus insertiondepth, can be set using the supplied union fitting.
