Feature: 1. The sensor probe adopts non‑contact induction, safe use and has long using life. 2. The stainless steel bracket is convenient to adjust the measuring head, and the light way must be unobstructed during adjustment. 3. Using high‑quality tinned shielded wire, fast and stable signal output, good performance. 4. Double nut installation, metal shell comes with M18×1 screw thread for fixed installation, convenient disassembly and assembly. 5. Strict quality control and quality assurance, high safety factor, can be used with peace of mind. Specification: Item Type: Non‑Contact Infrared Temperature Sensors Material: Stainless steel Purpose: Measuring water temperature, oil temperature, food, human body, ceramics, asphalt, rubber, chemicals, coal, graphite, metal, glass, etc. DC Power Supply: 10-30VDC Maximum Current: 50mA Output Signal: 4-20mA Equipment Power Consumption: ≤0.5W Measurement Accuracy: ±1% of the measured value or ±1.5℃, whichever is the largest Spectrum Range: 8~14μm Response Time: 150ms (95%) Optical Resolution: 20: 1 Emissivity: 0.95 fixed Working Environment: 0~60℃; 10~95%RH (no condensation) Cable Length: Approx. 1.5meter / 4.9ft Size: Approx. 18mm / 0.7in 32mm / 1.3in 68mm / 2.7in Output type Line color Function 4-20mA Red +24V 4-20mA Blue signal output 4-20mA+ . Package List: 1 x Sensor1 x Bracket Note: 1.This series of infrared temperature sensors have poor temperature measurement effects on bright or polished metal objects. 2.The metal surface needs to have a coating or oxide layer or paste high temperature tape to achieve accurate measurement results.
