The model CPT6140 high-speed pressure sensor is a compact, robust sensor with an output mode of 250 Hz (4 ms) response time and a measuring range which is freely selectable between -1 … +400 bar (-15 … +6,000 psi). The accuracy of up to 0.025 % IS-50 for 365 days makes the sensor suitable for a wide range of applications in precision measurement technology.

This precision pressure sensor is built into OEM instruments, e.g. in pressure, flow or humidity calibrators, or in any instrument where high-speed measurement is needed.

This pressure sensor is set up with streaming output mode in IEEE-754 format, and does not allow the user to send commands or queries in its native mode. It is used as a reference pressure sensor within the automated manufacturing of pressure measuring instruments or calibration stands. Through a high accuracy, speed of reading and long-term stability, the CPT6140 is particularly suited for applications in wind tunnels, in pressure chambers or for leak and burst tests. These characteristics make it a valuable tool in metrology, hydrology, oceanography, and in the aviation and space industries.


The model CPT6140 has an RS-232 interface as standard and an RS-485 interface as option. The sensor can be configured for gauge and absolute pressure for any measuring range within the specified limits.

With a recalibration time of 180 or 365 days (depending on accuracy selected) and a high resolution of 6 digits, the CPT6140 is flexible enough to be used in a wide variety of applications.

Compact design
With its robust and compact design, the pressure sensor can be easily integrated in a 19″ rack. With the combination of male and female threads, a fast and secure fitting is always possible, negating the need for further sealing.
