Description
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.
Application
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.
Functions
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.
