Pressure Sensors feature digital CANopen-BUS output.

Press Release Summary:

Melt and Industrial Pressure Sensors with digital CANopen-BUS technology converts low signal pressure sensing elements from analog to digital, then processes further in intelligent microprocessor. Scanning and conversion rate of pressure signal is 20 milliseconds. Digital pressure signal with 13 bit resolution is continuous on 2-wire CAN-BUS connection, and is controlled and analyzed by CANopen BUS protocol in parallel to BUS apparatus/controls.

Dynisco Introduces Pressure Sensors With Digital "CANopen-BUS" Output


Franklin, MA (December 2001)...Dynisco Instruments introduces digital CANopen-BUS technology in enhanced Melt and Industrial Pressure Sensors. These transducers provide the most sophisticated BUS control technology available and open many avenues for new applications.

The low signal of the pressure sensing element is converted from analog to digital and is further processed in an "intelligent" microprocessor. The scanning and conversion rate of the pressure signal is only 20 milliseconds, meeting the requirements for most industry applications.

The digital pressure signal with a high 13 bit resolution is continuous on the 2 wire CAN-BUS connection and it is controlled and analyzed by the CANopen BUS protocol in parallel to the BUS apparatus/controls or in the host systems. As a result of the CAN-BUS technology, the sensor-specific calibrations, e.g. zero balance and range, can also be programmed as the functions "Auto-Zero, CAL, ALARM, Zero Suppression and Range Extension".

The integrated CAN circuitry automatically scans the functions of the pressure transducer and sends a "life-guard" alarm when a problem arises.

The intelligence and capabilities designed into the CAN-open BUS structure and communication provides further functionality such as automated transducer calibration/limit-setting and pressure supervision both locally as well as centrally. In addition, necessary fine-tuning adjustments are significantly reduced as all peripheral equipment and sensors are included in the can-bus ring.

This results in an overall increase in process security of the complete control system as well as the facility itself. At the same time there is a saving of service costs that can be realized during the life of the facility, especially in large and decentralized systems.
