CECOMP C4101

Program to Measure Flow and Velocity LED Pressure Level Indicator and OLED Display Ranges from ±0.25 inH2O to ±40 inH2O Accuracies of ±0.25%, ±0.5%, or ±1% Mounts in Industry-Standard Openings Power: 24-120 VAC or VDC Two SPDT 8 Amp Alarm Relays Optional: 4-20 mA Isolated Output Example –200 to 200 millimeters H2O 4-20 mA output (programmable) Two SPDT 8 Amp relays (programmable) The C4000 series are microprocessor-based programmable digital differential pressure gauges with 2 SPDT alarm contacts. They measure positive, negative, differential pressure using an extremely stable piezoresistive sensor. They can be programmed to measure air flow and velocity when used with a pitot tube. A 4-20 mA isoated output is optional. The bright ½" high red LED display gives the gauges improved readability and precision. The OLED display is used to set up and indicate setpoints, deadband, units, and flow coefficients. The pressure level indicator LEDs are designed to mimic the indicating needle of a mechanical gauge. The LEDs will light up from left to right as the pressure moves away from zero. The C4000 series gauges are designed to be a direct replacements for mechanical gauges that use industry-standard openings ranging from 4-9/16" to 4-13/16" diameter. Eleven user selectable engineering units are available to give improved versatility and performance over mechanical gauges.
