KOBOLD brand new pressure relay PSC-232R2C3A
Meaning of each part of PSC-232R2C3A:
PSC: 系列代号 (Pressure Switch with digital display and Control outputs)
32: Specific measurement range code (corresponding to 0~16 bar)
R: Rotating display screen (easy to observe from different angles)
2: Output type code (2 independent switch outputs)
C: Electrical connection method (C represents cable connection)
3A: Special function combination (3 represents PNP transistor output, A represents G1/4 internal thread connection)
working principle
PSC-232R2C3A adopts the principle of thermal resistance measurement and detects pressure changes through a piezoresistive ceramic sensor
Pressure acts on the ceramic diaphragm, causing slight deformation
Deformation causes a change in the resistance value of the Wheatstone bridge on the membrane
The microprocessor converts resistance changes into precise pressure values (with a resolution of up to 0.01 bar)
Real time display of pressure values on a rotatable LED screen
When the pressure reaches the preset switch point, the corresponding transistor output state flips (PNP type: low level, high level)
Unique advantage: Two independent programmable switch points that can be set with different pressure thresholds and action modes, achieving multi-level monitoring and alarm
5、 Application Fields
Widely used in industrial scenarios that require precise pressure monitoring:
Hydraulic system: pump outlet pressure monitoring to prevent system overload
Pneumatic system: compressed air pressure control to ensure stable operation of equipment
Water treatment: pipeline pressure monitoring to ensure the safety of the water supply system
Cooling system: Monitor the pressure of cooling water flow to prevent equipment from overheating
Lubrication system: Centralized lubrication system pressure monitoring to ensure sufficient oil supply to each lubrication point
Compressor protection: Monitor the inlet and outlet pressure of the compressor to prevent abnormal working conditions
Automated production line: monitoring the pressure of pneumatic actuators to ensure production stability

Operation and Setting Guide
1. Basic operations:
After power on, the display screen shows the current pressure value (units can be switched: bar, kPa, psi, etc.)
Short press the SET key to enter the menu, and use the UP/DOWN keys to browse and set parameters
After setting up, long press the SET key to save and exit
2. Main setting parameters:
SP1/SP2: Pressure threshold for two independent switch points
HYS: Switch hysteresis (to prevent frequent switching)
MODE: Action mode (optional: Hysteresis mode, Window mode)
DELAY: Output delay time (0-300 seconds, eliminating brief fluctuations and interference)
OUTPUT: Output type (normally open NO/normally closed NC)
