SUPPLIED WITH THE FOLLOWING AS STANDARD

  • 10 Metres / 30 Feet Cable
  • Proof test certificate
  • Operator Manual
  • Carry/Storage Case

If you require a Load pin to a particular size and design,(Contact us for questionnaire

Often a customised design (Contact us) they are manufactured in-house from 17-4PH stainless steel and are normally supplied complete with an anti-rotation plate as a cabled solution.

Built to withstand the harshest environments in industries such as marine, offshore oil and gas or construction they are suitable for use in exposed situations and can be supplied as a subsea product with SubConn connectors to withstand immersion in seawater to extreme depths. For hazardous areas, we can supply a wireless ATEX or IECEx product for use in zones 0,1 and 2.

Straightpoint Loadpins are typically connected to Straightpoint’s range of handheld displays or may be supplied with a vast array of output formats to include mV/V, RS-422, RS-485, utilising the ASCII, MODBUS TRU and CAN-BUS protocols or an analogue output such as 4-20mA for PLC integration.

They are also supplied with a 10 metre / 32ft cable as standard however usable cable length varies greatly with lengths available to 1500 metres / 4900ft depending on the output format.

Load pin diagram

Description

A load measuring pin senses the force applied across it, via strain gauges installed within a small bore through the centre of the pin. Two grooves are machined into the outer circumference of the pin to define the shear planes, which are located between the forces being measured.

Load Pin Environmental Protection
As the instrumented area of the load pin is totally contained within a small central bore, the load pin sensor is inherently waterproof. Manufactured from special stainless steels, fitted with welded or `O' ring sealed end caps and with special attention to the signal cable glanding, a very high operating reliability can be guaranteed even for load pins operating underwater.

Load Pin Typical Locations
If a pin exists within a defined load path or can be fitted to experience a force, then a Straightpoint Load Pin can be installed to monitor that load. The sketches below show typical locations for load pins. 

Load pin applications

Load Pin Locking Systems

A load-measuring pin needs to be securely locked into position in order to fix its orientation with respect to its associated assembly. This needs to be fixed, both in the axial and rotation modes, to ensure that accurate and repeatable results are obtained from the system.

A standard load pin is designed to sense the force in one direction only. A force at right angles to that force will produce a zero output from the sensor.

Load pin locking system

Load Pin Cable & Connector Arrangements

The signal cable can normally exit from the load pin to suit the installation and space requirements. Emphasis should be placed on the protection of the cabling system from accidental damage during installation and use.

A plug and socket breakdown can be incorporated at the load pin if required. Extra protection can be provided over the standard polyurethane sheathed cable in the form of a hydraulic hose. This provides excellent protection with the advantage of an associated fit
