Ko'rib chiqish
Imkoniyatlar
Qurilmaning asosiy xususiyati — o’rnatilgan simsiz aloqa moduli bo’lib, u o’lchangan bosim ma’lumotlarini kabel o’tkazmasdan ma’lumot yig’ish va monitoring tizimlariga uzatishni ta’minlaydi.
BOSIM MONITORING REJIMI:
- Fon monitoringi: har 5 sekundda (sozlanadi) qisman uyg’onish bosimni belgilangan qiymatlar bilan solishtirish uchun; agar diapazon ichida bo’lsa — ma’lumot uzatmasdan uyqu rejimiga qaytish
- Favqulodda uzatish: bosim belgilangan qiymatlardan oshganda darhol ma’lumot uzatish
- Rejalashtirilgan aloqa: o’lchash va ma’lumot uzatish bilan to’liq uyg’onish (standart har 15 daqiqada)

Purpose
P-METER Ex is a specialized autonomous device for continuous pressure monitoring in industrial environments. Unlike universal ANALOG meter-switches, P-METER Ex features a built-in high-precision strain gauge pressure sensor made of 316L stainless steel and is optimized for minimal power consumption during pressure measurement.
Applications:
- Oil and gas industry — pipeline and wellhead pressure monitoring
- Water supply and sewerage — network pressure control
- District heating — coolant pressure monitoring
- Industrial automation — process control
- Mining industry — hydraulic system monitoring
Explosion protection: Marking 1Ex db IIC T5 Gb X / PB Ex db I Mb X — the device is designed for use in hazardous areas. Protection rating IP66.

Operating Modes
P-METER Ex supports an intelligent pressure monitoring mode optimized for maximum battery life:
1. Background Pressure Monitoring
Partial wake-up every 5 seconds (configurable) to compare current pressure against set thresholds. If pressure is within normal range — return to sleep mode without data transmission. This ensures continuous monitoring with minimal power consumption.
2. Alarm Transmission
Immediate data transmission to the server when pressure exceeds configured thresholds (upper/lower limit). Provides instant response to emergency situations.
3. Scheduled Communication
Full wake-up with measurement and data transmission on schedule. Default interval — every 15 minutes (configurable).
Background monitoring is a unique feature of P-METER Ex. The device checks pressure every 5 seconds but only transmits data when necessary. This enables a battery life exceeding 1,000,000 measurements.
Battery Life
