H3021P Transmitter for Compressed Air (temperature and humidity regulator)

Reference

Condition: New

Humidistat, thermostat with two relay outputs. For outdoor or indoor use.
Temp probe & Relative Humidity of hard anodized aluminum, for compressed air up to 25 bar with 1 m cable.
Cables lengths of 2m or 4m available optionally.

Humidity, temperature probe on a cable. Measured values also become another interpretation of humidity: dew point temperature, absolute humidity, specific humidity, proportion, specific enthalpy of the mixture.

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.
