Digital Pressure Transducer

linearity within the calibrated temperature range of 15-45°C. Thus, a calibrated CPT6010 operated
within its temperature band, and with proper zero and span settings, will provide accurate pressure
measurements.
The transducer should have the span verified periodically to insure its stability. Initially, the recom-
mended period between calibrations is as specified (180 days). This period may be extended as
confidence is gained in the span stability.
7.1 Environment
Whenever possible, calibrate the CPT6010 at the same ambient temperature as its normal oper-
ating environment. The temperature should be stable, and within the specified calibration range.
In addition, for maximum accuracy, see that the CPT6010 is at rest on a stable platform which is
free of vibration and shock, and oriented similar to its final installation attitude. At the factory the
CPT6010 is calibrated vertically with the pressure port at the bottom.
7.2 Equipment
The following equipment is needed to calibrate a gauge transducer (see Figure 7.2):
1. A downloadable calibration utility program. Go to http:\\www.mensor.com, click “Digital Library”,
click “Software”, click “Instrument software”, then click on Operating & Calibration software for
the CPT6xxx digital pressure transducer series of digital pressure transducers. The calibration
utility program is also available on CD by request.
2. A host computer with a serial port to match the CPT6010 (RS-232 or RS-485), software to run
the CPT6010 transducer, and an appropriate cable.
3. Appropriate pressure and vacuum sources and calibration reference standards for the
CPT6010’s pressure range.
4. Tubing and valves adequate for the pressure range.
Additional equipment required to calibrate sub-atmospheric transducers (absolute, vacuum or bi-
directional pressure types) is illustrated in Figure 7.2. These items are:
8. A vacuum pump capable of pumping down to 300 millitorr.
9. A vacuum standard to measure pressures down to 300 millitorr.
10. One additional valve to isolate the vacuum line.
