    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 Specifications 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 sensor. 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 DescriptionThe CPT6100 and the CPT6180 Digital Pressure Transducers are self-contained pressure sens-ing device that provides high accuracy pressure measurements. These transducers incorporate a low hysteresis silicon sensor with electronically compensated pressure linearity over the specified temperature range. Communication with the CPT6100 and CPT6180 is over a serial bus, either RS-232 or RS-485. Differences between the two products can be seen in the specification section.

    3.2 Turndowns

    The transducer has the capability to include two distinct ranges (turndowns) using a single sensor. The primary turndown is always the higher range of the transducer. At powerup the primary turn-down is active by default.

    3.3 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 IEC6010-1 3rd ed. compliant.

    3.4 Sensor

    The pressure sensor is a micromachined silicon strain gauge. The sensor is secured to the trans-ducer case.

    3.5 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.
