C is a transmitter designed specifically for measuring micro differential pressure in HVAC systems. Its core advantages include precise measurement, easy installation, and adaptability to industrial scenarios. The following is a summary of key information:

1、 Core positioning and applicable scenarios

-Specializing in micro differential pressure measurement, suitable for air and neutral gas media, widely used in HVAC systems.

-AO model features: with digital display screen (A=with display screen), active output mode (4~20mA or 0~10V), using 3/4 wire power supply (24Vac/VDC).

2、 Key technical parameters

-Range: -100~100Pa to -1000~+1000Pa (CP112 series standard range).

-Measurement accuracy: ± 1% measurement value, repeatability/linearity/hysteresis ± 3Pa, response time T63=0.3s, resolution 1Pa.

-Output and Power Supply: Supports 4-20mA (maximum load 500 Ω) or 0-10V output, power supply 24Vac/VDC ± 10%, power consumption 0.6VA (4-20mA) or 2VA (0-10V).

-Protection and Material: Industrial plastic shell (flame retardant UL94-V0), IP65 protection level, weight only 143g.

3、 Core functions and operational features

-Multi unit support: switchable between 8 measurement units including Pa, mmH ₂ O, mbar, inWG, etc.

-Convenient calibration: Manually calibrate the zero point through the "Autozero" button on the panel, with indicator lights and screen prompts during calibration.

-Flexible settings: Configure range, output signal type, and measurement units through internal toggle switches without the need for complex software.

-Easy installation: Comes with a back fixed backplate, rotate the transmitter to complete the fixation, and supports back outlet connection.

4、 Key points of use

-Working environment: 0~50 ℃ (non condensing), altitude 0~2000m, allowable overpressure 21000Pa.

-Wiring specification: It should be operated by professionals. When using 3-wire wiring, the output grounding terminal should be connected to the power input grounding terminal.

-Maintenance precautions: Avoid using irritating solvents containing formaldehyde during cleaning.
