💡 Key Summary: Portable Point Sensor Calibrator for On-Site Setup & Inspection Without External Power
YHSM-PSTG is a battery-powered portable setting and calibration device for point-type leak sensors. Once a sensor is connected, operators can check status on the LCD and perform sensitivity setting (fine adjustment) and inspection based on on-site conditions. It enables fast maintenance and commissioning even in areas where power is not readily available.
Portable Inspection & Setup Tool for On-Site Configuration and Calibration
Setting & Inspection Controller for All-in-One Electronic Leak Point Sensors
For commissioning after installation, periodic inspections, or re-setup after sensor replacement, the biggest bottlenecks are usually “power availability” and “bringing the right setup tools.” YHSM-PSTG runs independently on an internal rechargeable battery, allowing operators to check sensor status and set sensitivity on site even in areas without power.
🔋 Independent Field Operation Without Power Constraints
• Built-in rechargeable battery enables on-site setup and inspection without external power. (Up to 12 hours of continuous use on a full charge)
• Battery level can be checked on the LCD to help plan field work.
🎛️ Status Check & Sensitivity Setting (Fine Adjustment)
• View device status and setting values on the LCD monitor (33×60mm) directly in the field.
• Fine-tune sensitivity to match site conditions (humidity, washdown, temperature, surface condition, etc.) to reduce false alarms and missed detections.
🔗 Compatible Devices & Auto Recognition
• Supports setup and inspection for All-in-One Point Sensors (YHSM-A01 / YHSM-AR01).
• Also works with 1-Channel Control Modules (YHSM-01S series) to expand the scope of setup and inspection tasks.
• Automatically detects the connected device type, allowing work to start without complex setup.
"YHSM-PSTG reduces on-site setup and inspection time,
and helps standardize sensor maintenance and commissioning procedures."
