This UV Signal Dummy (UVSD) is used together with LPI and MPI sensor arrangements in Berson UV systems. The unit simulates a UV signal and allows the system to be tested or operated temporarily without a sensor connected, which is useful during fault-finding, calibration or sensor replacement. Resistance range is 1 kOhm to 6.1 kOhm, compatible with Berson systems that use UV intensity monitoring. Please get in touch if you are unsure whether this UVSD fits your UV system.
