H7430 relative humidity, temperature and atmospheric pressure transmitter with RS485 COMET output

Description

H7430 relative humidity, temperature and atmospheric pressure transmitter with RS485 output and two relay outputs for outdoor and indoor use.

The inverter is equipped with two relay outputs for displaying alarms or controlling external devices. It has three binary inputs to detect water, smoke, glass breaks or door contact.

The measured values can also be converted into other formats such as dew-point temperature, absolute humidity, specific humidity, mixing ratio or others. The device has a built-in capacitive polymer humidity sensor that ensures long-term stability of the humidity calibration, independent of the influence of water and condensation. The converter is useful for measurements in non-aggressive environments.

The H7430 contains a microprocessor-based control circuit housed in a rugged plastic enclosure with connection terminals. The sensor contains a stainless mesh filter. Computer processing allows long-term stability and error display.
