K-Tech Crosshead Load Weighing Sensor Kit

K-Tech crosshead sensors use an in-house built strain gauge mounted to your structural cross-member (typically your crosshead) to measure your platform or car when loaded with freight or passengers.

The crosshead sensor uses strain gauges mounted to a steel bar which is then bolted to your structural cross-member, typically your crosshead. This sensor bends proportionally to weight when a platform is loaded with freight or passengers. The sensor comes in a kit with specialized mounting hardware and a heavy-duty cover that is also used as a drill template for easy installation.

The crosshead sensor is wired to an electronic controller box that contains the sensor amplifier, power supply and configuration modules. The amplifier provides circuits to zero the signal from the sensor(s) and provides the necessary signal gain. Setup is achieved with push-buttons and a digital readout. The controller automatically adjusts the zero setting should the signal drift over time do to mechanical creep or temperature changes. The signal from the sensor can be adjusted to subtract tare weight (the weight of the container, ropes, traveler cables, etc) resulting in a weight-only voltage reading. Outputs are configurable for most applications including analog outputs, set points, 4-20 mA, and CanBus (all model specific options).

 

Features of the Crosshead mount sensor and controller are

  • One sensor units are available for <10 stories or <100 foot shafts
  • Dual sensor unites are available for >10 stories or >100 foot shafts
  • Digital readout for adjustments and monitoring
  • Push-button setup in as little as 5 minutes
  • Setpoints can be adjusted without weights
  • Auto-zeroing for maintenance free operation
  • Field selectable to reflect 'hanging' or 'in-car' weight
  • Outputs configurable for most controllers
  • Field adjustable analog and setpoint systems
  • Custom outputs available built to customer specs including 4-20 mA and CanBus
  • NEMA rated enclosures available
