WP-6002 Wireless Pressure Transmitter

Low-power wireless pressure transmitter with NB-IoT / 4G options; scheduled or alarm-triggered reporting, configured and monitored through a web portal.

Key Features

• Multi-network connectivityOne hardware platform, four radio options: 4G (multi-band, region-specific), NB-IoT, LoRaWAN and Zigbee. The variant is fixed by the model code, so the same instrument can be deployed across regions with different network coverage.
• Ultra-low power designTransmit current ≤ 50 mA and sleep current ≤ 10 µA at 3.6 V DC. The instrument stays in sleep mode and wakes only to measure and report, which is what allows the whole unit to run from a single lithium cell.
• Scheduled and alarm-triggered reportingData are uploaded on a fixed interval, and an alarm report is sent as soon as pressure crosses a configured limit, so the interval does not have to be shortened just to catch events.
• Remote configurationReporting interval, alarm thresholds, zero adjustment and device parameters are set from the web page. No local push-buttons, no laptop on site, no opening the enclosure.
• Local OLED displayA 128 × 64 OLED shows the live pressure value and device status, so an operator standing at the installation can read the measurement without logging in.
• Rugged, sealed construction316L stainless steel diaphragm, aluminium alloy housing, FKM sealing ring and silicone fill fluid; vibration 20 g and shock 50 g tested to IEC 60068-2-6 and IEC 60068-2-27.

Applications

System Architecture

The transmitter is one node in a three-tier system. At the field tier, the WP-6002 measures and uploads over NB-IoT, 4G or LoRaWAN (a LoRaWAN gateway is used where the site has no cellular coverage). At the platform tier, a server receives the MQTT payloads, stores every record in a database and raises alarms in real time. At the application tier, the customer opens a PC browser or a mobile terminal on the platform address to see current values, statistics and trend curves, and to push configuration back down to the instrument.

The platform tier can be the free cloud service supplied by the factory, or the customer's own system reached through the third-party API option.

The transmitter sends its readings to the sensor data platform over NB-IoT, 4G or LoRaWAN. The platform raises alarms in real time and writes every record to a database automatically, so the site can be followed as it happens and any period can be recalled later — an alarm is known within minutes, not at the next site visit.

Users log in to the platform address from a networked PC or a smartphone to read instrument data, run statistics and analysis, and generate reports and trend curves — clear, accurate and fast.
