Watching air water vapour content in grain storage
Keeping a close eye on ambient air water vapour content within grain storage sites is the role of Hawco's Rense range of temperature and relative humidity sensors
Keeping a close eye on ambient air water vapour content within grain storage sites is the role of Hawco's Rense range of temperature and relative humidity sensors, together with associated instrumentation.
Hawco offers a complete suite of RH and temperature assemblies, sensor probes, transmitters and indicators designed to provide a high level of precision measurement, long term stability and fast response.
Typical of the Rense family is the Series 730 multi-purpose, duct or wall-mounted 2 or 3/4 wire relative humidity transmitters.
Operating with thin film, capacitive sensor technology, immune to most reagent vapours, these transmitters continually measure the ambient humidity and provide an analogue output directly proportional to the RH.
The 2-wire model provides a passive 4-20mA output, while the 3/4-wire design is user-selectable: 0-1V, 0-5V, 0-10v or 0-1mA.
The RH Transmitters are available in a standard accuracy of 2%RH or as a low-cost version with an accuracy of 3%RH between 30%RH and 80%RH.
They can also be combined with a temperature transmitter or a single Pt100 or Pt1000 element.
