Pneumatically operated actuator for operation of accelerator, brake and clutch pedal in vehicles. External set-point of the pedal actuator position and brake pedal force via analog voltage to closed-loop pressure regulator in external valve box. Fast, simple and robust installation on vehicle driver seat. EMC resistant actuator in fail-safe design with mechanical, spring-actuated return to idle position in power-less situation. Due to the pneumatically operation there are no electrical wirings into the vehicle and no EMC emissions. The actuator uses non-metal materials were possible. The system can be expanded by additional pneumatically operated actuators for ignition key or push buttons.

High precision vacuum pressure control valve for exhaust emission analyzer. Temperature proof up to 180 °C and acid resistant against exhaust of combustion engines. Constant vacuum pressure even at high pressure peaks at inlet (for example generated by turbo combustion engines) Outlet pressure: 0.9 at (0.1 bar below atmosphere) Outlet pressure deviation: approx. 70 mbar Inlet pressure: max. 3 bar (4 at) Different outlet pressure ranges and other flange versions can be offered.

Safety switch for detection of un-usual motions of vehicles on chassis dynamometer. Integration into local Quick stop and emergency stop loops. A safety switch which is sensitive in push, pull, vertical and horizontal excitations, mounted to a flexible arm on a solid base plate, is simply placed closed to the vehicle. Potential free NO and NC contacts. Different versions with different fixture sizes can be offered.

Independent sensor system to measure the surface velocity of a chassis dynamometer. Precise measurement of vehicle speed for correlation tests on chassis dynamometer. Simple set-up to roller. Spring-loaded compensation of vibrations and roll surface inconsistencies. Integrated encoder with TTL pulse output. For analog signal conversions a programmable F/U converter SmartTach can be offered.
