Aperçu
Fonctionnalités
La caracteristique cle de l’appareil est un module de communication sans fil integre qui assure la transmission des donnees de pression mesurees aux systemes de collecte et de surveillance des donnees sans necessite de cablage.
MODE DE SURVEILLANCE DE PRESSION :
- Controle en arriere-plan : reveil partiel toutes les 5 sec (configurable) pour comparer la pression avec les seuils ; si dans la norme – retour en veille sans transmission de donnees
- Transmission d’urgence : envoi immediat des donnees lorsque la pression depasse les seuils configures
- Communication programmee : reveil complet avec mesure et transmission des donnees (par defaut toutes les 15 min)

A wireless pressure transducer designed for automatic monitoring, control, and management of industrial processes. It converts gauge pressure into a digital signal and transmits encrypted data packets over a LoRaWAN wireless network.
Fig. ROSSMA IIOT-AMS P-METER Ex — autonomous wireless pressure transducer
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.
Certificate of conformity TR CU 012/2011: EAEU RU C-RU.АЯ45.В.00306/25 (valid until 02.12.2030).

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
Estimated autonomy (14 Ah battery)
| Mode | Autonomy |
|---|---|
| 15-minute transmission interval (no monitoring) | 76 months (~6 years) |

WARNING: The device is equipped with a non-rechargeable lithium-thionyl chloride (LiSOCl₂) battery. Attempting to recharge the battery may cause a fire!
