Introduction of temperature switch

Industrial thermal resistance (PT100, PT1000)is taken as a temperature sensor which is normally used with display indicator, recording instrument and electronic regulator. It can directly measure the  temperature of liquid, steam, gas medium and solid surface in production process from -50 ℃ to 200 ℃.


TTS71 is an intelligent temperature switch combining temperature measurement, display and control together. The sensor output signal is amplified, noise reduced and conditioning through a highly integrated TM's processor to realize accurate temperature measurement, display and control of the switching output. 


The protection is IP65, the product's amplifier circuit has over-voltage, over current and reversed polarity protection. It can be used in complex electromagnetic environment of industrial sites. It has diversified output options including analog output (4mA ~ 20mA DC) +2 way PNP, 2-way PNP, 2-way or one-way relay. 

Also it supports manually cleared and switchover of the measuring unit between ℃ and ℉ . OLED screen displays real-time temperature value and switch status. It is with flexible installation, easy operation and simple menu. TTS71 temperature switch is safe and stable, and it can be widely used in industries such as water utilities, petrochemical, metallurgy, transport, electricity, machinery manufacturing etc.
