4 Transmitter Installation (Electrical)
Use a cable with strain relief to ensure proper electrical connection and to reduce stress on the connectors.
The power supply input is +14 to +30 VDC, with a nominal supply voltage of 24 VDC. Damage may occur to the
circuitry if excessive voltage is applied, polarity reversed (beyond -60V), or if a wrong connection is made.
4.1 Input/Output Wiring
To comply with EN61326-1 immunity requirements, use a braided, shielded cable. Connect the braid to the metal
hoods at both ends of the cable with the end for power supply connected to earth ground.
4.2 Electrical Connection Schematic
Ensure a low impedance electrical connection between the transmitter body and the grounded
vacuum system to shield the sensor from external electromagnetic sources.
Ensure that the analog output is connected to floating input.
