Vaisala HMP233 Humidity and Temperature Transmitter Description

Functions

Measures relative humidity and temperature with high accuracy using capacitive sensors in environments from -40 to +180°C. Provides analog/digital outputs, calculates dewpoint and other humidity parameters. Features automatic calibration, sensor purge for chemical contamination, sensor warming for condensation prevention, and measurement reliability in extreme conditions. Suitable for climate chambers, industrial processes, pharmaceutical manufacturing, and meteorological applications requiring precise environmental monitoring.

Platforms

This fixed-mount transmitter accurately measures relative humidity and temperature in industrial, HVAC, and cleanroom environments. It interfaces with process control systems, outputting analog (4-20mA, 0-10V) or digital (RS-485 Modbus RTU) signals. Integration is typical with PLCs, DCS, data loggers, and SCADA systems. It operates on a low-voltage DC power platform. Common applications include environmental chamber monitoring, building automation, and critical climate control in pharmaceutical or food processing.

Applications

Precise environmental control and monitoring in HVAC systems, cleanrooms, data centers, and laboratories. Essential for industrial process optimization in pharmaceuticals, food processing, and semiconductor manufacturing, ensuring critical humidity and temperature regulation. Used in meteorological stations, agricultural research, and OEM integration into climate chambers and drying equipment for reliable data acquisition and control.

Accessories

10-35 VDC power supply; M12 8-pin female circular connector cable for power input and RS-232/RS-485 serial or 4-20mA/0-10V analog outputs; Vaisala HMP230 series probe cable for sensor connection; USB configuration cable for PC interface. Interfaces include M12 8-pin male circular connector (data/power) and proprietary probe interface for sensor element.

Interfaces

4-20 mA analog output with 2-wire loop powered configuration, RS-485 serial communication interface with Modbus RTU protocol, M12 8-pin circular connector for power and signal connections, terminal block option available for hardwired installations, operating voltage 7-35 VDC, digital output configurable for alarm functions, probe connection via fixed cable assembly, weather-resistant IP65 rated housing with cable gland entry

Specifications

Provides high-accuracy relative humidity and temperature measurement, often with calculated dew point, for industrial process control, HVAC, and cleanroom environments. It integrates with SCADA/BMS/PLC systems via configurable analog (e.g., 4-20mA, 0-10V) and digital (e.g., RS-485 Modbus RTU) outputs, utilizing terminal blocks or M12 connectors. Common applications include environmental monitoring and critical process climate control in pharmaceutical, food, and manufacturing sectors.
