Dynamometer testing often occurs at very high or very low temperatures. High reliability and availability are key metrology criteria used in engine test benches.
The Vaisala BAROCAP Barometers and HUMICAP Humidity and Temperature Transmitters provide wide operating ranges that cover virtually all test conditions. For condensation conditions, a cable probe with heating is offered. Other options include graphical display of logs and measurement trends, data acquisition and transmission, and flexible calibration. A 3-in-1 combination air pressure, humidity and temperature transmitter is also available.
