Overview
The SMC ZSE30-T1-65 is a high-precision digital pressure switch featuring a 2-color LCD display and advanced monitoring capabilities. The SMC ZSE30 Series is a high precision, 2-color display digital pressure switch used for detecting and displaying pressure, performing switch operations, and detecting abnormal conditions. The T1 variant includes NPT 1/8″ piping connection (M5 female thread), making it compatible with standard industrial pneumatic systems. This unit is supplied in used condition and has been tested to ensure reliable operation.
Key Features
- 2-color digital display allows selection according to application requirements with four different display settings available.
- LCD display shows current pressure, setting mode, selected display unit, and error codes; 2-color display (Green OUT1 and Red OUT2) lights up when respective switch output is turned ON.
- Anti-chattering function to prevent false detections from pressure fluctuations.
- Power-saving mode to reduce consumption; resolution-switch function and MPa/kPa switch function for unit conversion.
- Can be used for vacuum/low pressure and positive pressure applications with fluids such as air, inert gas, and non-flammable gas.
- Uses a lead wire for electrical connection with standard lead wire length of 2 m.
Technical Specifications
The ZSE30-T1-65 is configured for positive pressure operation with pressure range capability from 0 to 1MPa. The unit features dual switch outputs (OUT1 and OUT2) with programmable hysteresis and window comparator modes. Display options include fixed MPa units or switchable MPa/kPa display. The 65 suffix indicates the configuration variant within the ZSE30 series.
Typical Applications
- Pneumatic system pressure monitoring and control
- Compressor discharge pressure regulation
- Vacuum system supervision for industrial automation
- Process control requiring precision pressure detection
- Equipment protection and shutdown circuits based on pressure limits
