The new Yokogawa CA700 Portable Pressure Calibrator is equipped with a silicon resonant sensor that uses Yokogawa proprietary DPHARP technology. The CA700 can measure pressures with an accuracy that is within ±0.01% of rdg, the company says.
The portable pressure calibrator features a variety of functions, including a wide selection of measuring ranges, as found/as left data storage, and memory capacity to store calibration procedures. It provides an accurate and efficient calibration and verification tool for pressure/differential pressure transmitters and other types of field devices for commissioning or regular inspection, the company says.
"As the result of a growing awareness of the need for safety and stability in plant operations, increased attention is being paid to the maintenance and inspection of field devices," said Chris Costlow, Yokogawa's sales and marketing manager of meters and instruments for North America. "There is a strong need for portable pressure calibrators like the CA700 that operate efficiently and perform to a high standard."
The CA700 is able to store the calibration procedures for pressure transmitters and switches in its internal memory. It also records data and error rates before and after calibration. The stored data can be used for purposes such as analysis of device performance and determination of maintenance frequency.
