SLD1xx Series Vibration Transducers
Piezoelectric accelerometers for permanent installation — top and side entry
- Part number
- SLD144 / SLD144S
- Brand
- SPM Instrument
Compression-type piezoelectric accelerometers with built-in electronics, designed for vibration monitoring of industrial machinery. The electrical signal is isolated from the transducer housing. Choose by cable entry: top (SLD144) or side (SLD144S).
Highlights
- 100 mV/g sensitivity, 2 Hz – 10 kHz linear frequency range
- 600 m/s² (60 g) max. peak acceleration
- Optional temperature measurement on SLD144 (−20 to +120 °C)
- Stainless acid-proof steel casing, IP66/67
- Case isolated (>10 MΩ), max. 100 m cable
The transducer is installed on a flat machine surface and connected with a twisted pair cable. Mechanical fastening uses mounting studs (accessories) through an M8 tapped hole, available in M6, M8, M10 and UNF 1/4" thread sizes.
SLD144 offers an optional temperature measurement. Used with the Intellinova Parallel EN online system, the transducer measures temperature in the −20 to +120 °C range. Measurement is performed above 10 kHz, where it does not interfere with the acceleration signal.
SLD144S has side entry and a captured bolt for installation; it requires a flat surface at least 30 mm in diameter (at least 16 mm when using mounting base 15757, 15802 or 17769).
In moist environments, use the sealed connector with integrated measuring cable (46162 / 46163) together with cable protection tube 81385.
