Manufacturer: Galltec Mela Sensortechnik
Hygrometer and temperature sensor for industrial usage - GG, KC, ZC series
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.

Install the MELA®- humidity/temperature sensors in a place where characteristic climatic conditions can be measured. We recommend to use the MELA®-ZA 24-type mounting plate (product info sheet no. F 5.1) for wall or duct-mounting. The specifi ed 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 self heating of the sensor. The sensor can be installed in any position. However, do not position it in a position where water ingress can occur. Dew formation and splashes do not damage the sensor, although corrupted measurement readings are recorded until all the moisture on and directly around the sensor element has dried up. In order to maintain interference immunity in accordance with EN 61326-2-3 when it is in use, we recommend to use a screened cable (type recommended: 8x AWG26 C UL order no. 5339) for connecting the sensors, and have this fi tted into the sensor’s EMC heavy-gauge conduit thread by a qualifi ed electrician. In order to check functioning in the place of installation, we recommend that you use theMELA®-ZE31/1-type humidity standard with a ZE 33-type auxiliary adapter (product info sheet no. F 5.2). Dust does not cause any harm to the humidity sensor, however, it does affect dynamic performance. The protective filter should only be screwed off carefully to check functioning with a humidity standard. It is important not to touch the highly sensitive sensor element in the process. If necessary, soiled fi lters can be screwed off and rinsed. When you screw them back on, bear in mind that sensors will not measure accurately again until they are completely dry. Sensors of the series .../9 can be completely and carefully cleaned in distilled water. It is not possible to exchange the PTFE fi lter on the humidity sensor element.
Please consult the application instructions for the sensing elements (product info sheet no. A 1) or check with
the manufacturer for further information which you need to bear in mind when using humidity sensors with capacitive sensing elements.
(series ZC.D and ZC.HD), do not apply a torque in excess
of 25 Nm.
