In-place pressure transmitter calibration made easy

March 12, 2003
Low-pressure transmitter features the SpoolCal™ process valve actuator, which allows the transmitter to be easily validated and calibrated in-place without disturbing process tubing or wiring in critical airflow conditions. With a simple twist of the wrist to the left, the SpoolCal tees the process pressure out to a handheld calibrator. A twist to the right puts the user in the calibration mode. The front access test jacks provide on-line reference signal without removing wiring, avoiding signal interruption. The signal offers added features with 2:1 turndown and range status LEDs for instant troubleshooting information. Ashcroft® SXLdp low-pressure transmitter.
