Wireless monitoring & control · Since 2004
Battery-powered sensors that deliver live pressure, temperature and alarm data from remote and hazardous sites — no cables, no mains power. Proven in the field since 2004.
What we do
We design and build wireless sensors that measure pressure, temperature, humidity and load, then deliver the readings to your screen in real time. They run for years on a single battery, form their own radio network, and keep logging even when the connection drops. When a reading crosses a threshold you set, the right person gets a text or an email. You see problems the moment they start, not days later.
Two platforms
The technology should fit the problem, not the other way round.
Proprietary mesh radio
Mercury is our proprietary low-power mesh radio. Self-forming networks, long range, and certified for explosive atmospheres to ATEX Zone 0. Built for the sites nothing else reaches: wellheads, pipelines and off-grid installations.
Up to 12 years battery life, product dependent.
Bluetooth
Our newer platform, built on Bluetooth. It connects to standard devices and existing systems, deploys quickly, and covers the monitoring and control work that doesn't need Mercury's long range or hazardous-area certification.
Connects to standard devices and existing systems.
Case studies
If it needs measuring and there's no easy way to wire it, we've probably done something like it.
Oil & gas wellheads
Live pressure and temperature from wells with no power for miles.
Oil & gas wellheads
Solar-powered controllers with battery backup, backhauling over GPRS or satellite. Every reading is written to memory on the sensor itself, so a dropped link costs you nothing — around six weeks of logging is held onboard.
Fracking instrumentation
Real-time pressure instrumentation for hydraulic fracturing sites.
Fracking instrumentation
Sensors certified to ATEX Zone 0, IECEx and CSA. The mesh forms itself as units are placed, so the instrumentation moves with the site instead of being wired into it.
Emergency shut-in (ESIS)
Shut in a well from up to 1 km away, keeping operators upwind of danger.
Emergency shut-in (ESIS)
A self-contained system. The radio handset closes the well on a two-stage press-and-confirm over a 128-bit AES encrypted link, running on its own battery pack rated for 10 years. Built for brownfield sites already using hydraulic surface-controlled valves.
Pipeline monitoring
Gateways form their own network along the line: monitoring with no fixed infrastructure.
Pipeline monitoring
Gateways backhaul over Ethernet, serial Modbus into SCADA, GSM, or Iridium satellite — whichever the location allows. The mesh spans the run without trenching or fixed infrastructure.
Welding monitoring
Live data from welding processes, without cabling the shop floor.
Welding monitoring
Monitoring that goes where the work is, without running cable across a live shop floor. Runs on our Bluetooth platform.
Industrial monitoring
Pressure, temperature and humidity across plants and process lines.
Industrial monitoring
Pressure, temperature, humidity and load across plant and process lines, with Modbus or JSON at the edge for whatever system you already run. Rated from −40 to +80 °C ambient.
Clinical cold chain (BluBug)
Continuous temperature compliance for blood banks and clinical fridges, with a full audit trail.
Clinical cold chain (BluBug)
Continuous monitoring for blood banks, fridges and freezers, with temperature mapping, in-transit logging and an audit trail built for MHRA, FDA and CPA scrutiny. Calibration rolls on a swap-out warranty.
Lockers
Live in NHS hospitals, where staff share lockers across alternating shifts.
Lockers
Deployed in NHS hospitals, running on our Bluetooth platform. Access is managed across shift handovers, so a locker shared by two clinicians on alternating shifts is always open to whoever is on, and the bank stays secure and interconnected.
Remote & off-grid sites
Solar, GSM and satellite backhaul for sites with no power and no network.
Remote & off-grid sites
Where there is no cellular coverage at all, Iridium satellite carries the data instead. Solar panels with battery backup run the gateway, so the site needs no mains supply.
Field proof · Abu Dhabi
In April 2009 we fitted wireless pressure and temperature sensors to six free-flowing wells for ADCO: remote desert sites with no power, where soft sand made cable-laying impractical. In the first six months the system captured 98.7% of the theoretical maximum data. After 11 months a sensor was removed and checked against a reference; it measured within 0.5% of its original specification, and no adjustment was needed. The system is still running.
Distribution
Our partners hold stock and know their own ground. Everywhere else is supplied direct from Emsworth, where the kit is built, calibrated and where the awkward questions land.

No partner near you
It rarely matters. Most of this kit is commissioned from Emsworth regardless, so tell us what you are monitoring and we will work the supply route out afterwards.
New distributors
The network is still growing. If you already sell instrumentation into an industry or a country we have not reached, we would rather hear from you than not. Consultancy, royalty and OEM arrangements are all possible.
Why us
Sensors go onto plant that is already running. Fitting, maintenance and battery changes need no interruption to production.
UKAS-traceable certificates supplied with the sensor, from temperature-controlled baths and pressure generators in a fully automated system.
Return-to-base recalibration runs through the product’s life: physical condition checks, seal replacement and a new battery, then a fresh certificate.
When a battery finally goes, the module changes out inside a hazardous area without breaking the process connection.
Made and proven in Emsworth
CSA hazardous-area approval and intrinsic-safety rating, marked on the unit.
Boards populated on our own surface-mount line.
Radio modules fitted to our own boards.
Stainless pressure fittings, assembled on jigs.
Pressure testing, rated to 10,000 psi.
Sensor diaphragm assemblies, staged for build.
