eyc-tech THS30X Series Multifunction Temperature & Humidity Transmitter

Product catalog summary

Overview: The THS30X series by EYC-Tech is an industrial temperature and humidity sensor known for its high accuracy and long-term stability. It features temperature compensation and linear calibration, with options for analog output or Modbus RS-485 communication.

Specifications: The sensor operates with a power supply of DC 8-35 V or AC 12-30 V. It supports a temperature range of 0 to 50°C for the wall type (THS301) and -40 to +80°C for duct (THS302), remote (THS304), and outdoor (THS307) types. Humidity measurement ranges from 0 to 100% RH. The device offers a linear accuracy of ±0.2°C and a nonlinear error of ±1.8% RH.

Features: The THS30X series includes a capacitive humidity sensor and Pt 100 class A for temperature measurement. It provides a response time of less than 20 seconds with a membrane filter and less than 30 seconds with a sintered filter. The device is equipped with an LCD module for display, showing data with a character height of 5.56 mm.

Applications: This sensor is suitable for HVAC processes, air conditioning, environmental ventilation control, and various industrial applications such as building management, hospitals, clean rooms, laboratories, storerooms, cooling tanks, environmental chambers, weather stations, indoor pools, greenhouses, livestock nurseries, pharmaceuticals, textiles, agriculture, food, manufacturing, and drying facilities.

Installation and Protection: The housing is rated IP65, while the probe is IP20. It includes electrical protections against reverse polarity, over-voltage, and short-circuit. Installation options vary by type, with wall, duct, remote, and outdoor configurations available.

Connectivity: The device supports RS-485 and analog connections, with options for M12 or M16 cable glands. It is important to ensure common grounding when connecting with RS-485 to avoid damage.

Ordering Guide: The ordering guide provides options for selecting the type of installation, signal output, display, electrical connector, filter type, and remote probe cable length.

Certification: The product is CE certified and complies with ISO 9001 standards. Calibration reports are available from YUDEN-TECH CO., LTD., accredited by ILAC/TAF.
