Ashcroft CXL Differential Pressure Transmitter

Differential Pressure Transmitter
CXL

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).

• Rugged ABS package capable of DIN rail or standard panel mounting
• LED power status indicator to assist in trouble shooting, correct wiring or quickly locating the instrument on a duct
• Detachable Euro style terminal block reduces wiring errors and field wiring time
• 20 standard pressure ranges all capable of withstanding 15 psi without damage or calibration change
• Digitally compensated. NIST traceable 0.4% F.S. and 0.8% F.S. accuracy models
