Commissioning
The solenoid valve of the EM-AUTOZERO extension module is integrated into the tubing of the static differential pressure transmitter and connected to the differential pressure sensor of the air terminal unit. EASYLAB and TROX UNIVERSAL controllers provide a zero point adjustment at regular intervals. For this purpose, the measuring tubes of the differential pressure transducer are temporarily short circuited, then the zero voltage is measured. This measured value is used as a correction value for the volume flow rate measurement until the next zero point correction.
This specification text describes the general properties of the product. Texts for variants can be generated with our Easy Product Finder design programme.
Extension module for EASYLAB or TROX UNIVERSAL controllers based on TCU3 for automatic zero point adjustment. Long-term stable volume flow rate measurement and reduced maintenance. The expansion module comprises a solenoid valve, the connection cable and connection tubes.
