Pacific Sensor Technologies offer the PST-H3020 temperature+ humidity, Humidistat, with two relays temperature, humidity, pressure regulators, relay outputs and options of 4 to 20mA and RS485 outputs.
The PST-H3020 temperature+ humidity, Humidistat is designed for two-state control such as heating, ventilation, humidifier and dehumidifier.
The PST-H3020 temperature+ humidity transmitter is equipped with two relay outputs for alarm indication or control of external devices.
Each relay can be assigned to any measured or computed value. The fully equipped transmitter contains temperature, humidity and pressure sensors.
It recalculates measured temperature and relative humidity to other humidity interpretations such as dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy.
Reading and pressure output are available in these units: hPa, kPa, mbar, mmHg, inHg, inH2O, PSI, oz/in2. Degrees Celsius and Fahrenheit are user selectable. Parameters are adjustable from regulator keyboard or from the computer.
The PST-H3020 temperature+ humidity transmitter has a large dual line LCD for simultaneous display of temperature, pressure or relative humidity or other calculated humidity interpretation.
The PST-H3020 temperature+ humidity transmitter features capacitive polymer sensor, which ensures calibration long term stability, inertia against water and condensation. The transmitter is designed for use in non-aggressive environment.
The transmitter can be optionally equipped with three binary inputs for detection of two-state events, for example, water, smoke, glass break detection and door contact.
The PST-H3020 temperature+ humidity, Humidistat, can be used in the following applications:
- temperature and humidity control
- monitoring of temperature, humidity, pressure and three binary signals at building management and automation, server rooms, telecommunication devices, warehouses, glasshouses, manufacturers, museums, archives, galleries, air-conditioned rooms, HVAC and weather stations
