Greisinger GHTU-1K-MP Vlhkomerný/teplotný vysielač s výstupom 0-1V

High-precision humidity and temperature transmitter with capacitive humidity sensor and Pt1000 temperature sensor, delivering 0-1V DC outputs for both parameters. The sensor tube is IP65 rated, while the housing is IP40, and the sensor connects via a 1-meter fixed cable.

Overview

The Greisinger GHTU-1K-MP (model 602650, EAN 4016138845341) is a compact transmitter designed for industrial and HVAC applications. It measures relative humidity from 0 to 100% RH and temperature from -20 to +80°C, converting these into linear 0-1V DC signals. The capacitive humidity sensor ensures fast response, while the Pt1000 element provides accurate temperature readings.

What stands out

• Humidity accuracy of ±2.0% RH (10-90% RH, 10-40°C)
• Temperature accuracy of ±0.3°C (10-40°C)
• Fast response: t90 < 10 s for humidity, < 30 s for temperature (with metal protection cap)
• Wide supply voltage range: 12-30 V DC, low current consumption approx. 5 mA
• Robust sensor tube: Ø 14 mm x 100 mm, IP65 protection
