What is a calibrator used for? Calibrators are used to validate and adjust the accuracy of field instrumentation, which can deteriorate over time due to harsh environmental or process conditions, leading to plant shutdowns and thus opportunity costs, or personnel injury. The calibrator and control ensure that instruments are performing reliably and accurately by sourcing and measuring precision signals. Yokogawa offers an extensive portfolio of handheld calibration equipment, including process multimeters, pressure calibrators, and multifunction process calibrators. Yokogawa's process calibrators are trusted for their:
The CA500 and CA550 are high-performance, multi-function calibrators designed for use in multiple applications. Featuring useful functions for field work, these multi-function calibrators help you calibrate field instruments with improved source and measurement accuracy.
The CA700 is a highly accurate and highly functional pressure calibrator specifically designed for the calibration of differential pressure and pressure transmitters, which are widely used in plant processes these days and are improving in terms of accuracy and functionality.
Two High-Performance Hand Pump Models Available
Designing an instrumentation system for high current measurement requires careful consideration of the trade-offs associated with each type of sensing device. The purpose of this application note is to help engineers understand the sensing choices available and the corresponding trade-offs with each technology.
The CA700 Portable Pressure Calibrator from Yokogawa Test&Measurement is equipped with a silicon resonant sensor that uses Yokogawa proprietary DPHARP technology to measure pressures within ±0.01% of rdg accuracy, making it one of the most accurate portable pressure calibrators on the market. This highly accurate 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. The Yokogawa Test&Measurement CA700 is an accurate and efficient calibration and verification tool for pressure/differential pressure transmitters and other field devices.
FieldMate is PC and tablet based software for adjusting, setting and managing devices. It systematizes a series of work from field calibration of a pressure / differential pressure transmitter to report generation in combination with the Pressure Calibrator CA700. They achieve speedy, highly efficient field calibration by offering calculation of relative error, pass/fail determination and report generation as well as automatic recording of device information and calibration data. Recorded calibration data can be registered in FieldMate' s database (device maintenance information) along with other maintenance information. CA700 and FieldMate, "Smart Calibration" significantly reduce the man-hours for calibration.
