1.1 Warranty

All products manufactured by Mensor are warranted to be free of defects in workmanship and

materials for a period of one year from the date of shipment. No other express warranty is given,

and no armation of Seller, by words or actions, shall constitute a warranty. SELLER DISCLAIMS

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 trans-

ducers.

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 trans-

ducer case.

3.4 Circuitry

All of the circuitry is included on a single PC board. The combined pressure and temperature sen-

sor 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 infor-

mation 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.

4. Specications

Accuracy specications presented herein are obtained by comparison with primary standards

traceable to the National Institute of Standards and Technology (NIST). These specications are

obtained in accordance with the ISO Guide to the Expression of Uncertainty in Measurement

(GUM). The calibration program at Mensor is accredited by the American Association of Laboratory

Accreditation (A2LA) as complying with both the ISO/IEC 17025:2005 and the ANSI/NCSL Z540-1-
