Mipeg Crane Sensors

Model Load hoist and moment sensors, Boom angle sensor

Frequency-based strain sensors and Ex-certified boom angle sensors for Mipeg crane load monitoring systems.

Description

Mipeg load hoist and moment sensors use a frequency-based S-sensor, in which the natural frequency of a vibrating S-shaped strip varies with tension. The sensor is welded to the crane structure and hermetically sealed according to MIL-STD-883-A. The boom angle sensor, mounted in the boom foot, converts boom angle to operating radius.

Key features

  • Strain sensor gauge length 40 mm, nominal frequency 1600 Hz
  • Withstands 10 times overload; error less than ±1% of rated range
  • Temperature range -30 ºC to +80 ºC
  • Certified for hazardous zone 1 (Atex II2 GD EEx d IIB T6)
  • Boom angle sensor: 133 x 133 x 128 mm cast aluminium housing (approx. 4 kg), Atex and IECEx Ex zone 1, IP66/67, -40 to +65 ºC

Applications

Load, moment and radius measurement for Mipeg safe load indicator systems on offshore and vessel cranes.
