This document is the operating instructions for the electronic temperature sensor TK7480, and introduces the product's function characteristics, installation, electrical connection, setting and other information.
This manual describes the IFM TK7480704475 electronic temperature sensor, which detects system temperature in machines and equipment and provides two output signals (normally open and normally closed) with adjustable set points. It outlines the measurement range, sensor element (Pt1000, DIN EN 60751 B‑class), and key functional features such as a fixed hysteresis of 5 K.
The document covers mechanical installation (G½ NPT pipe connection, maximum tightening torque 25 Nm), electrical wiring (qualified electrician, power supply 9.6‑32 V DC, rated current 500 mA), and detailed setting procedures for the two set points. Technical data including accuracy, repeatability, dynamic response time, housing materials, IP67 protection, and environmental limits are also provided. This manual is written in Chinese.
