C 4.7 Humidity/-temperature sensors for industrial applications up to 200°C, up to 25 bar Description MELA®-humidity/-temperature sensors in this series are supplied with a robust aluminium die cast housing with an inox or aluminium sensor part to measure relative humidity or relative humidity and temperature in air and other non-aggressive gases for a working temperature range of up to 200°C. The pressure-proof executions „D“ and „HD“ can be used at pressures up to 25 bar, at temperatures up to 125°C or up to 160°C. These sensors are ideally suited for industrial applications, e.g. in drying processes. The advantages of the series .../9 are its improved dynamics, in particular at low air speeds and also its increased service life, even under more challenging operating conditions (pollutant impact or permanent humidity > 95 %rh). When air speeds are extremely high combined with a high number of particles, using the series .../9 is not recommended.

Product info sheet no. C 4.7 page 2 User instructions Install the MELA®- humidity/temperature sensors in a place where characteristic climatic conditions can be measured. For attaching them into ducts or wall bushings, we recommend to use the MELA®-ZA 24-type mounting plate (product info sheet no. F 5.1). The specified minimum air speed and - with current output - the load according to the operating voltage (diagram) should be complied with. Deviations may lead to additional measuring faults resulting of the selfheating of the sensor. The sensor can be installed in any position. However, do...
