Straightpoint Loadpins LP

Description

The Straightpoint range of Load Measurement Pins (LMP`s) are designed for use in applications where an end of line load cell cannot be used when an integrated solution is required.

PRICES ON APPLICATION

Requires connection to Straightpoint`s Handheld plus (HHP), Desktop Controller data logging software (DCP10M) or External Amplifier range (SA-3420) that can be configured to provide outputs such as 4-20mA, 0-10v, 0-5v for PLC or data logger integration.

Often a customised solution they are manufactured from high tensile stainless steel and are normally supplied complete with an anti-rotation plate as a cabled or wireless solution.

Built to withstand the harshest environments in industries such as marine and offshore oil and gas they are suitable for use in exposed situations and can be supplied to withstand immersion in seawater to extreme depths.

Straightpoint Load pins are typically connected to Straightpoint`s Handheld plus 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 output format.

Please note: Please advise cable configuration on order – Radial or Axial pin exit.

Loadpin General Description
A loadpin 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.

Loadpin 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.

Loadpin Cable & Connector Arrangements
If wireless options are not preferred a 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 hydraulic hose. This provides excellent protection with the advantage of associated fittings being readily available.
