GZW50/150 vibration and temperature sensor
Independent vibration and temperature outputs, limits and ordering configuration for the mining sensor.
On this page
The output-impedance entry is printed as <500Ω2.5. The trailing 2.5 has no confirmed meaning and must not be treated as a valid unit or silently removed. The specifications and ordering table also list different temperature-range choices; confirm the supplied configuration.
Independent measurement circuits
GZW50/150 measures temperature with a PT100 platinum resistance element and vibration with a piezoelectric sensor. The stainless-steel housing contains independent vibration and temperature signal circuits. Each measurement has a separate two-wire 4–20 mA output.
The source describes the instrument as intrinsically safe for mining and gives the marking Ex ib I Mb. This article reports the source marking without verifying certificate validity.

Selection fields
The ordering structure is GZW50/150-A(V/G/D)-B-C-D-E-F.
| Field | Listed options |
|---|---|
| A: vibration range | V01 = 0–10 mm/s, V02 = 0–20 mm/s; G01 = 0–10 g, G02 = 0–20 g; D01 = 0–100 µm, D02 = 0–200 µm; further ranges indicated |
| B: mounting | 01 = M10 × 1.5; 02 = M8 × 1.25; 03 = 1/4–28; 04 = magnetic base; 05 = custom |
| C: cable | 01 = 1 m; 02 = 2 m; 03 = 3 m; further lengths indicated |
| D: leads | 00 = direct cable; K = armored; 01 = circular connector |
| E: temperature span | 01 = 0–100 °C; 02 = 0–150 °C; 03 = −50 to 150 °C; 04 = −50 to 100 °C |
| F: temperature-probe insertion | 00 = no rod; 01 = 10 mm; 02 = 20 mm; continuing to 10 = 100 mm |
The operating-temperature limit in the technical table is distinct from an ordered temperature measurement span. Confirm the insertion depth and mechanical drawing for the monitored machine.
