NKHT3S-A-F-TTCNT Temperature and Humidity Transmitter User Manual
The NKHT3S-A-F-TTCNT series transmitter measures indoor temperature and humidity and converts the readings to frequency‑output signals. It uses a humidity‑sensitive capacitor and a microcontroller for linearization, eliminating the need for an A/D converter, which allows direct computer acquisition of temperature and humidity values. The device is designed for wall‑mount installation with a hidden wiring module at the rear.
Technical specifications include humidity accuracy of ±3% RH at 25 °C (40‑60 % RH), temperature accuracy of ±0.5 °C, frequency output ranging from 0‑+50 °C (1‑1.5 kHz) and 0‑100 % RH (1‑2 kHz), a 5 V DC supply (10 mA), and an operating temperature range of –10 °C to 50 °C. The transmitter must be powered for 40 minutes before testing, and testing must be performed with the unit held upright. This manual is written in Chinese.
