Introduction

Principle & Structure

The TT21 contains a thermocouple probe, and the electrodes of the thermocouple are composed of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, thermoelectric potential will be generated, and the thermoelectric potential corresponds to the temperature value. The standard probe is K, E, T division, and other divisions can be provided according to user requirements.

Features

Simple installation, a variety of ranges are available, and probes of various specifications are available

Compact structure, wide range (-200...600℃)

High pressure resistance, can reach 100bar

A variety of graduation numbers are optional

Optional cabinet-mounted control table for connection use

application

Suitable for measuring water, oil and gas media

It can be used in water supply system, hydraulic and pneumatic system, cooling system, heating system, air conditioning system, automation engineering, etc.
