SPM Instrument 40100

Product Highlights

Shock pulse transducers can be used in permanent SPM installations for bearing monitoring. They are installed in countersunk mounting holes on the bearing housings.

A shock pulse transducer converts the shock pulses emitted by the bearing into electric signals. SPM supplies a range of shock pulse transducers with various adapters and tools for installations anywhere.

The shock pulse transducers come in different series, each containing various sizes.

The shock pulse transducer 40 000, 42 000, and 44 000 series

The shock pulse transducers come in different series, each containing various sizes.

The 40 000 series

Shock pulse transducers in the 40 000 series are used in permanent SPM installations for bearing monitoring. They are installed in countersunk mounting holes on the bearing housings. A shock pulse transducer converts the shock pulses emitted by the bearing into electric signals. A coaxial cable connects the transducer with a measuring terminal or measuring device. Maximum cable length is 4 m (extendable to 100 m with external TMU).

Transducer housing and base are made of stainless acid-proof steel, suitable for aggressive environments. Standard thread size is M8, with UNC 5/16" as an alternative. Standard length (A) is 61.5 mm. A long transducer (B), length 115.5 mm, is used to reach bearing housings beneath protective covers. The transducer is usually connected with a TNC plug. A TNC angle plug can be used in narrow spaces. To prevent cable corrosion in moist environments, the coaxial cable must be connected with a sealing TNC plug.

The 42 000 series (shock pulse transducers with TMU)

The shock pulse transducers with TMU (the 42 000 series) are used in permanent SPM installations for bearing monitoring, in cases where the cable length between transducer and measuring unit exceeds 4 m. The transducer with TMU (= Transducer Matching Unit) is installed in countersunk mounting holes on the bearing housings, in the same way as the 40 000 transducer. A shock pulse transducer with TMU 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. Maximum cable length is 100 m.

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 usually connected with a TNC plug. A TNC angle plug can be used in narrow spaces. To prevent cable corrosion in moist environments, the coaxial cable must be connected with a sealing TNC plug.

The 44 000 series

The shock pulse transducers in the 44 000 series are used in permanent SPM installations for bearing monitoring. They are installed in countersunk mounting holes on the bearing housings. A shock pulse transducer converts the shock pulses emitted by the bearing into electric signals. A coaxial cable connects the transducer with a measuring terminal or measuring device. Maximum cable length is 100 m.

Transducer housing and base are made of stainless, acid-proof steel, suitable for aggressive environments. Standard thread size is M8, with UNC 5/16" as an alternative. The extended transducer can be used to reach bearing housings beneath protective covers. The transducer is usually connected with a TNC plug. A TNC angle plug can be used in narrow spaces. To prevent cable corrosion in moist environments, the coaxial cable must be connected with a sealing TNC plug.
