Yokogawa Meters and Instruments releases new pressure calibrator

Yokogawa Meters and Instruments Corp. has released a new pressure calibrator suitable for the oil, gas, petrochemical, chemical, iron and steel, pulp and paper, electric power, and water supply and wastewater treatment industries.

The portable CA700 features a variety of functions that enable the efficient calibration of pressure/differential pressure transmitters and other types of field devices. The calibration of high-precision field devices requires calibrators that deliver greater accuracy and high performance. Yokogawa developed the CA700 pressure calibrator to meet these needs.

The calibrator is equipped with a silicon resonant sensor and can measure pressures with an accuracy that is within ±0.01% of reading (rdg). It can also output and measure current and voltage within ±0.015% of rdg. The CA700 is suitable for testing both pressure and DC input/output, which is essential for calibrating pressure transmitters and other devices.

For more stable and efficient calibration, 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, thus improving device maintenance.

The CA700 comes in three models with different measurement ranges: -80-200 kPa (kilopascal), -80-1,000 kPa, and -80-3,500 kPa.
