Series 261 Structural Pressure Test Controller (SPTC)
Achieve precise control of pressurized airflow throughout demanding cyclic pressurization tests of aircraft and spacecraft cabins and structural components. Easy to setup and operate, Series 261 units integrate seamlessly with AeroPro software and FlexTest controllers to deliver reliable, accurate and repeatable closed-loop pressure control that can be synchronized with other structural test loading.
Works in concert with pressurized air supply and a system controller to deliver tight, closed-loop pressure control
Integrated / Synchronized
Integrates seamlessly with the complete MTS portfolio of aerospace structural test solutions
Easy, Intuitive Use
Features intuitive front panel and provides easy test configuration and setup
Efficient Operation
Over-pressure circuit mitigates potential damage from excessive structure pressure

* The maximum structure pressure specified is the maximum designed level for the SPTC in the local mode. For a maximum structure pressure less than 0.69 MPa (100 psi), the required maximum structure pressure must be specified at the time of order.
† The pressure accuracy rating depends on the calibrated range of the proportional valve and the accuracy of the external feedback device.
