Diaphragm compression load cells
Scotload’s diaphragm load cells are ideal for a range of structural and industrial applications where height may be limited.
Manufactured from high tensile stainless steel, our diaphragm load cells have a low profile and high resistance to offset loads.
The standard fixing arrangement includes six counter bored holes with an optional base plate, which allows the load cells to become an integral part of the structure they are monitoring. They can also be supplied with tapped holes for more specialist installations.

How long will it take to dispatch?
Most of our stock is already in stock, available for immediate dispatch. Larger capacity load cells will often take around 2-3 weeks until dispatch. If you need it sooner than this, please contact us for more information – an express service is available.
What is the range of your wireless system?
With SmartLoad®, you can achieve 350m (direct line of sight) using our wireless handset. If you need more than this, SmartLoad® also offers a range of transmitters and receivers to enable you to receive load out information well over 3000m. And if you need further than this, our wall mounted display also offers output via Ethernet, meaning you can essentially relay this information anywhere on the globe with an internet connection.
What connections does SmartLoad® have?
None. Our system is fully wireless (we do have wired version which are not SmartLoad® variants). That being said, these can be connected to either a PC or wall mounted display (options) which offers a range of standard connections you can utilize.
Is a calibration certificate supplied?
Yes – a full calibration certificate is supplied, valid for 1 year from date of issue
Do I have a warranty with my load cell?
Yes – a standard 1 year manufacturer’s warranty is included. For extended warranty packages, please contact us for more information.
Is it shipped with batteries?
For UK orders, yes. For orders overseas, we recognize that often the batteries will actually delay being processed in customs and therefore we do not ship these with batteries. If you would like these however, please state this and we will ensure they are shipped along with your load cell.
