H3021P compressed air temperature and humidity regulator

code: H3021P

Humidistat, thermostat with two relay outputs. T+RH probe from hard anodized duralumin for compressed air up to 25 bars with 1m cable. Cable lengths 2m or 4m available optionally. Outdoor, indoor use.

Humidity, temperature probe on a cable. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.

Features

Humidistat is designed for two-state control of e.g. heating, ventilation, humidifier, dehumidifier, etc.
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. For each relay setting of delay, hysteresis, audible alarm is enabled.
Measured temperature and relative humidity is recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy.
Parameters are easy adjustable from regulator keyboard or from the computer. Large dual line LCD for simultaneous display of temperature, relative humidity or other calculated humidity interpretation is an advantage.
State-of-the-art capacitive polymer sensor ensures excellent calibration long term stability, inertia against water and condensation. Transmitter is designed for use in non-aggressive environment.

T+RH probe from hard anodized duralumin with 1m cable. Cable lengths 2m or 4m available optionally.

HUMIDISTAT APPLICATIONS

- temperature and humidity control
- monitoring of temperature, humidity:

building management and automation
server rooms
telecommunication devices
warehouses, glasshouses
manufacturers
museums, archives, galleries
air-conditioned rooms, HVAC
weather stations
To set regulator easily by the user from the PC program buying of SP003 cable is necessary - see Optional accessory.
Free configuration program TSensor for regulator adjustment is ready to download anytime.
It is also enabled to adjust regulator from the instrument keyboard.
If different adjustment of relay outputs is required, please specify required output values (RH, T, Tdp, ..) in the order. Adjustment is free of charge.
