OPTIONS
• Option XDL:
LED for quick process diagnostics:
Zero Pressure.........Center Amber LED
In Range ± .............Adjacent Green LED’s
Out of Range ± ......Adjacent Red LED’s
Includes: front access test jacks for on-line data
access without disturbing wiring
• Option XNL: Front access jacks without LED’s
• Option XPV: Available on pressure ranges up to
50IW maximum, SpoolCal™ process valve actuator
provides in-place system calibration without disturbing
process tubes. From Off position the removable
SpoolCal™ actuator tool provides the following functions:
- A 90 degree clockwise rotation puts the DXLdp in
the CAL mode isolating it from the process and
allowing direct external pressure input
- A 90 degree counter clockwise rotation puts the
DXLdp in the MONITOR mode to tee the process
pressure to the DXLdp sensor and out, providing
external measurement or recording capabilities.
Includes SpoolCal™ actuator tool with 7˝ silicon
tubing (as shown in front photo). (Refer to
Ashcroft® ATE series calibrator for data collection
and instrumentation)
• Option X21: 2:1 turn down, 0.25% accuracy is
maintained on initialized range
• Option XCL: Special range calibration
• Option XX1: Fast response (10msec)
• Option XX2: Slow response (1sec)
