Industrial Ethernet Temperature, Humidity, Pressure Sensors Hx53x With Relay Outputs
- temperature
- barometric pressure
- relative humidity
- dew point temperature
- absolute humidity
- specific humidity
- mixing ratio
- specific enthalpy
- three binary inputs
Transmitter is equipped with three binary inputs for detection of two-state events - e.g. water, smoke, glass break detection, door contact. Fully equipped transmitter contains temperature, humidity, pressure sensors. Measured temperature and relative humidity is recalculated to other humidity interpretations - dew point temperature, absolute humidity, specific humidity, mixing ratio or specific enthalpy.
Reading and pressure output available in these units: hPa, kPa, mbar, mmHg, inHg, inH2O, PSI, oz/in2. Degrees Celsius and Fahrenheit are user selectable.
Large dual line LCD for simultaneous display of temperature, pressure or relative humidity or other calculated humidity interpretation is an advantage. Parameters are easy adjustable from transmitter keyboard or from the computer.
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.
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.
Easy creation of online data acquisition system from Ethernet sensors by using new low cost database software Comet DBS Sensor Monitor - see also Accessories.
