Plug & Test® Force / Torque Indicators & Remote Sensors


The Plug & Test® family includes a series of interchangeable indicators and remote force and torque sensors. Indicators are sensors are sold separately. Mark-10 indicators feature graphic displays, blazing fast sampling rates, and a host of other features. For special applications, customer-supplied sensors can be easily field-adapted to our indicators via the uniquely flexible PTA configurable adapter.
