Introduction

Principle & Structure

TK71 is an all-electronic structure, the output signal is amplified and processed by a high-precision, low-temperature drift amplifier, sent to a high-precision A/D converter, converted into a digital signal that can be processed by a microprocessor, and the processed signal controls the two-way switch , to monitor and control the temperature of the control system.

Features

Simple installation, a variety of specifications probe optional, all stainless steel shell, compact and sturdy structure. And optional cabinet-mounted control table. Temperature preset switch point and hysteresis switching output. The switching value can be arbitrarily set between zero and full scale.

application

Gas-liquid dual-purpose type, can be used in water supply system, hydraulic system, pneumatic system, cooling system, heating system, air conditioning system, automation engineering, etc.
