Strain Gages – HITEC Sensor Developments

With over 45 years of strain gage instrumentation experience, HITEC Sensor Developments provides a range of tailored strain gage sensors using their approved strain gage supplier base.

Strain Gages with Pre-Attached Leads

Any model strain gage can be tailored with pre-attached leads. Using the approved strain gage supplier Let, HITEC offers strain gage sensors with pre-attached leads so as to prevent the requirement for soldering, thereby saving both time and cost and also guaranteeing quality.

Custom Weldable Strain Gages

Complementing the high temperature strain gage instrumentation support services, custom manufactured weldable temperature sensors and strain gages are available for custom use where standard sensors are not suitable based on conditions that cannot accommodate clamping and curing. Weldable strain gages need marginal surface preparation and self-contain environmental protection since the sensor is bonded to the component with the aid of the spot weld technique.

Weldable strain gages suitable for high temperature environments are fixed to a stainless steel carrier, pre-wired and then coated for best extreme environment strain measurements. Typically, it is also possible to pre-form these weldable strain gages if required.

Shim material typically used is 0.005” Inconel or 0.005” Nichrome so as to attain best results. Lead wire options at any length can include:

  • 0.062’ AWG SST Braided Type K
  • 0.040’ D Inconel sheathed Type K
  • #28 AWG SST Braided alumel/alumel
  • #28 AWG SST Braided Type K
  • Or customized to user specification
