2. Safety Notices

2.1 Warnings and Caution Notices

Not explosion proof. Installation of this instrument in an area requiring
devices rated as intrinsically safe is not recommended.

Some ranges require clean, dry, non-corrosive pressure media. See “Media

Compatibility” in the Specications section of this manual. This instrument

is not designed for oxygen use.

Caution: ESD PROTECTION REQUIRED. The proper use of grounded work
surfaces and personal wrist straps are required when coming into contact
with exposed circuits (printed circuit boards) to prevent static discharge to
sensitive electronic components.

Avoid excessive overpressure to the transducer. Externally mounted relief
valves to provide overpressure protection are available from Mensor as
optional devices and are highly recommended for very low pressure trans­ducers.

3. Product Description

3.1 General Description

The CPT6140 High-Speed Pressure Transducer is a self-contained pressure sensing device that
provides high accuracy pressure measurements. The CPT6140 gives a streaming output at 250Hz
from a low hysteresis silicon sensor with electronically compensated pressure linearity over the

specied temperature range. Communication with the CPT6140 is over a RS-232 or RS-485 serial

bus.

3.2 Power Supply

The required 12VDC power enters via J1. The power supply used to power the device must be a
limited-energy device supplying less than 8.3A at 12VDC. It is recommended that the power supply
is IEC 61010-1 3rd ed. compliant.

3.3 Sensor

The pressure sensor is a micromachined silicon strain gauge. The sensor is secured to the trans­ducer case.

3.4 Circuitry

All of the circuitry is included on a single PC board. The combined pressure and temperature sen­sor signals are routed to the signal conditioning electronics.

3.5 Serial In/Out Communications

Figure 3.6 - Serial In/Out Communications

CPT6140 Operating Instructions 9

High-Speed Pressure Sensor

CPT6140

The serial bus is set to either RS-232 or RS-485 at the factory. The bus is a two way communication

path used to receive commands and return measured pressure values and other transducer infor­mation to the user. This port is also used to transmit calibration adjustments and other user func-

tions to the transducer. Pressure units for each transducer are specied by the customer. Wiring

requirements for the serial port are provided in the Installation section and a list of valid commands
and responses (Table 6.5.4) is provided in the operation section.
