SPM Instrument 42100
Order #: 42100
Mfg #: 42100
The shock pulse transducer with TMU is used in permanent SPM installations for bearing monitoring, in cases where the cable length between transducer and measuring unit exceeds 4 m. This allows a cable length of max. 100 m. The transducer with TMU is installed in a countersunk mounting hole on the bearing housing, in the same way as a standard transducer.
A shock pulse transducer with TMU (TMU=Transducer Matching Unit) converts the shock pulses emitted by the bearing into an electric signal, and stabilizes the signal for transmission via a long cable. A coaxial cable connects the transducer with a measuring terminal or measuring device.
Transducer housing and base are made of stainless, acid proof steel, suitable for aggressive environments. Thread size is M8, with UNC 5/16" as an alternative.
The transducer is normally connected with a TNC plug, SPM 93022. In moist envirnments, the coaxial cable must be connected with a sealing TNC plug, SPM 13008. A TNC angle plug, SPM 93077, can be used in narrow spaces.
