Comet H3531 – Thermometer Hygrometer, Temperature and Humidity Sensor

• H3531 Thermometer Hygrometer Sensor with Ethernet Interface and Relays
• Equipped with two relay outputs for alarming or controlling of external devices
• Dew point and computed quantities
• SNTP protocol – time synchronization
• History export to CSV
• Temperature and humidity

Ambient humidity, temperature Ethernet sensor on cable with two relay outputs.

Sensor H3531 is designed for online monitoring of temperature, relative humidity of air without aggressive substances. Three binary inputs to detection of two-states signals are the advantage. Other devices are controlled by two relay outputs.

High precision capacitive polymer sensor ensures excellent long-term calibration stability and ultimate accuracy. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy.

The device is supplied with a T+RH probe with a 1m cable. Cable lengths 2m or 4m are available optionally.

Monitoring systems of the Hx531R line are designed for online monitoring of temperature in °C or °F, relative humidity of air without aggressive ingredients, barometric pressure, and three binary inputs for detection of binary signals. Measured temperature and relative humidity are recomputed to the following humidity expression: dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy. It is possible to set correction for altitude (pressure offset) and to choose one of the following pressure units: hPa, kPa, mbar, mmHg, inHg, inH2O, PSI, oz/in2. The device is equipped with two relay outputs for alarming or controlling of external devices. It is possible to assign any input value to each relay, to set comparing limit, delay, hysteresis, and acoustic alarm, or change its status by far control with using of Modbus communication protocol. The device is communicating through Ethernet interface. The device is internally separated into two units. The first unit provides measurement and controlling of output relays – there is possible to change these parameters directly through device’s keys or TSensor software. The second unit provides all Ethernet services, its configuration is possible through Telnet terminal or TSensor software (this setting is impossible to change through the device’s keys).
