ZSE30A(F) / ISE30A Series High Precision Dual-Color Digital Pressure Switch

Brand: SOLH by Richge Technology

Product Positioning

     SOLH ZSE30A(F) / ISE30A series high-precision digital pressure switches are used for real-time pressure monitoring, threshold alarm and closed-loop signal control of all pneumatic circuits. Compatible with vacuum, compound mixed pressure and standard positive pressure working conditions. Core advantages include ±0.2%FS ultra-high precision, dual-color red/green LCD display and one-click batch parameter copy function, acting as the "visual monitoring eye" of automated pneumatic systems.

Series Classification by Pressure Measurement Range

Core Technical Specifications (High Precision Grade)

  1. Display Unit: 4-digit LCD screen, dual color auto switch (Green / Red); OUT1 corresponds to green, OUT2 corresponds to red

  2. Measurement Accuracy: ±0.2%FS @25℃, resolution up to 1/1000 full scale

  3. Signal Output Options

     -- Switch signal: 2-channel NPN / PNP open collector transistor output (OUT1 & OUT2)

     -- Analog signal (optional): 1~5V voltage output or 4~20mA current output

  4. Power Supply: 12~24 VDC ±10% wide voltage range

  5. Overpressure Withstand Capacity

  6. ZSE30A / ZSE30AF: 500 kPa

  7. ISE30A positive pressure model: 1.5 MPa

  8. Protection Class: IP40 dustproof

  9. Operating Ambient Temperature: 0 ~ 50℃

  10. Exclusive Function: One-click parameter copy, copy settings from 1 master unit to maximum 10 slave units, effectively avoid parameter setting errors during batch equipment debugging

Complete Model Naming Rule

  Model Example: ISE30A-01-N-M

     --  ISE30A / ZSE30A / ZSE30AF: Series pressure type identifier

     -- 01: Port thread specification = M5 internal thread (R1/8)

     -- N / P: Switch output transistor type

        N = NPN open collector; P = PNP open collector

     -- M / C / D: Output combination definition

        M = 2 independent switch output channels only

        C = 1 switch channel + 1~5V analog voltage output

        D = 1 switch channel + 4~20mA analog current output

Dual-Color LCD Display Logic

     -- Green backlight: Actual pressure within user preset normal working range

     -- Red backlight: Pressure exceeds upper / lower alarm threshold (overpressure / underpressure warning)

     -- 4 adjustable display modes: Support standard logic (normal green, abnormal red) or reverse color switching logic as required

Typical Industrial Application Scenarios

  1. Pneumatic Cylinder & Workpiece Clamping Circuit

     Set clamping pressure threshold 0.5~0.7MPa; trigger red alarm signal once pressure drops below lower limit to prevent workpiece loosening during processing.

  2. Vacuum Suction Handling Station (ZSE30A vacuum dedicated model)

     Set reliable adsorption threshold ≤ -80kPa; immediately output alarm signal if vacuum degree deteriorates to avoid workpiece falling off during transfer.

Performance Comparison vs Ordinary Mechanical Pressure Switches

Step-by-Step Selection Guide

     -- Vacuum only or mixed vacuum + micro positive pressure → Choose ZSE30AF universal compound pressure model

     -- Standard general pneumatic circuit (0.4~0.7MPa air supply) → Most popular model ISE30A-01-N-M

     -- Require real-time continuous pressure data collection by PLC → Select C (1~5V voltage) or D (4~20mA current) analog output variant

One Sentence Summary

     SOLH ZSE30A vacuum, ZSE30AF compound and ISE30A positive pressure digital switches feature ±0.2%FS high precision dual-color LCD, 2-channel NPN/PNP switch + optional 1~5V/4~20mA analog output with one-click batch parameter copy, widely used for clamping pressure and vacuum suction monitoring & alarm in automated pneumatic equipment.
