Developed for automotive engine bench tests this high-performance transmitter bridges the gap between rugged field durability and elite calibration-level data resolution

The PX-25H features continuous onboard temperature profiling. This digital compensation matrix actively corrects for localized thermal shifts in real time, preventing zero-point drift and span sensitivity variations during fast temperature ramps. Housed in a robust, corrosion-resistant 316L stainless steel enclosure, the sensor provides a rapid response time and premium resistance to field vibration or mechanical shocks.

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.
