Keller Company High-Speed Pressure Sensor Series 21PHB
High-speed pressure sensor optimal for measuring pulsations and unsteady behavior.
The pressure sensor series 21PHB is a compact pressure sensor capable of measuring not only static pressure but also dynamic pressure with a bandwidth of 20 kHz. It can be used for both liquids and gases. It features a built-in amplifier that outputs a 0-10V analog signal. The small sensor head (pressure receiving part) with M6 fine thread can be used at temperatures up to 100°C, and it has a pressure resistance of up to four times the measurement range. 【Features】 〇 Capable of measuring dynamic pressure with a bandwidth of up to 20 kHz in addition to static pressure (ideal for measuring pulsations and unsteady behaviors) 〇 Built-in amplifier type with 0-10V analog signal output 〇 Sensor head can be used up to 100°C 〇 ±0.1% FS accuracy (achieves ±0.5% FS even in the temperature range of -10 to 80°C) 〇 Welded structure type without internal seals 〇 Compact design, pressure connection with M6 x 0.5 fine thread 〇 Robust structure (IP67), ideal for use in test benches 〇 Allows temperature reading and zero adjustment using RS485 interface (please contact us for details)
