Model CXLdp Differential
PressureTransmitter
BULLETIN CT-6
FEATURES
Rugged ABS package capable of DIN
rail or standard panel mounting
LED power status indicator to assist
in trouble shooting or quickly locating
the instrument on a duct
Detachable Euro style terminal block
reduces wiring errors and field wiring
time
19 standard pressure ranges all
capable of withstanding 15 psi with-
out damage or calibration change
Digitally compensated, 0.4% F.S. and
0.8% F.S. accuracy models
NIST traceable
The Ashcroft CXLdp transmitter uses
the patented Ashcroft Si-Glas variable
capacitance sensor. This MEMS sensor
provides extraordinary sensitivity and long
term stability. New digital compensation is
accomplished using a highly reliable
application specific integrated circuit (ASIC).
