1. Product Overview
The KY3002TS Digital Temperature Switch is an electronic temperature measurement and control device that integrates temperature sensing, real-time display, signal output, and control functions into a single unit. It employs high-precision sensors (such as PT100 platinum resistance) and fully digital circuit boards to convert temperature signals into switching outputs, while an LED digital display provides real-time readings of the current temperature.
Core Features:
LED/LCD Real-Time Display: Intuitive reading of current temperature, eliminating display value errors.
Field-Adjustable Switch Points: Users can freely set the action point and hysteresis via buttons.
High Switching Speed: Up to 300 switching operations per second, ensuring fast response.
Multiple Output Types: Offers various switching outputs including PNP, NPN, and relay options.
