In Vehicle Mini Pressure Sensors

Interface proudly offers DDM’s innovative range of sub-miniature pressure/flow sensors to the UK automotive industry.

DDM’s sensors are primarily designed for on vehicle testing in extreme climatic conditions ranging from -40⁰C to +125/150⁰C but may also be used for bench use. All sensors feature a fully welded stainless steel construction. Pressure ports and electrical connectors can be user-specified to best fit your application.

Pressure ranges start at 0.1bar, up to 2,000bar, with working temperature ranges from -40⁰c to +125/150⁰C and Total Error Band to <0.25%.

DDMS' PV-15B brake pressure sensor is designed for automotive R&D engineers working with the hydraulic braking system of ICE, Hybrid or Electric Vehicles. The PV-15B is a small, light, weight pressure sensor designed to be mounted in the hydraulic system of vehicles whether they use disc or drum braking systems. The small form factor of the PV-15B enables it to be mounted in the smallest, most confined spaces. It’s also temperature and vibration resistant with a high burst pressure of 400 bar ensuring accurate and reliable pressure measurement.

The VCT is a turbine measurement system tailor-made for the flow measurement of almost any liquid, including agressive or flamable liquids. The VCT is ideally suited for road tests and in testing complex thermal management in vehicles with electric motors. The DDM turbine flow meter has a media-contacting thermocouple (VCT) has been specially developed for this purpose. The VCA flow computer processes data from the VCT flow sensor and converts it to a 0-10v signal for conection to an external DAQ. The compact size of both the flow sensor and flow computer means they can be easily installed, even when space is restricted.
