Fixed Installation Decibel Meter SLT-TRM

Decibel meter for fixed mounting with relay and regulation output

The decibel meter consists of a measuring microphone with a handle and a wall mount with a 1.5 cm cable, a sound transmitter. The main application area of this decibel meter is for continuous sound measurements and sound control in factory halls, production rooms, and leisure pavilions (nightclubs, public parties, ...). 

The limit value for the alarm output can be programmed on the indicator.

The analog output signal can be used to operate window flaps or store transmitter signals in a logger, to be later evaluated and documented. The decibel meter is very easy to connect and operates at 230 V mains.
