CHT series temperature and humidity transmitters are high-performance OEM value-added products based on proven HIH3610 thermal-set polyester capacitive humidity sensor and HEL700 series PT1000 platinum resistor, with measurement range of 0-100%RH, temperature measurement range of -20°C-+85°C or -10°C-+60°C, 4-20mA or 0-5V output, and PCB or wall-mounted installation.
The CHT series transmitter measures humidity from 0‑100%RH and temperature from -20 °C to +85 °C (or -10 °C to +60 °C) using a HIH3610 capacitive humidity sensor and a Pt1000 temperature sensor. It offers 4‑20 mA two‑wire or 0‑5 V three‑wire output, high linearity, long‑term stability, and IP30 protection.
The device can be mounted on a PCB or installed on a wall with a dedicated heat‑dissipation channel. Power requirements are 7.5‑36 VDC for 4‑20 mA output (nominal 24 VDC) or 10‑30 VDC for 0‑5 V output (nominal 12 VDC). The manual includes wiring diagrams, dimension drawings, and warranty information. This manual is written in Chinese.
