Field Instrumentation
Accurate field instrumentation is the foundation of every safe and efficient industrial process. Every measurement point whether a pressure transmitter on a separator vessel, a temperature sensor on a heat exchanger, a level instrument on a storage tank, or a differential pressure gauge on an HVAC filter feeds critical data to the control system that the safety and productivity of the entire facility depends upon.
ConnectSys Automation supplies a comprehensive range of field instrumentation for pressure, temperature, level, flow, and air quality measurement covering both ATEX and IECEx certified instruments for hazardous area applications and cost-effective solutions for general industrial, water treatment, and HVAC environments across the UAE and GCC.
Differential Pressure Transmitters & Switches
4-20mA DP transmitters and adjustable DP switches for filter monitoring, fan status, and flow indication. Available in Ex versions.
Differential Pressure Gauges
DP gauge measures positive, negative, or differential pressure. HVAC filter monitoring and duct pressure.
Zener Barriers & Galvanic Isolators
IS interface devices for Ex i field instruments DIN rail mounted in safe area control rooms.
Every IS loop requires these.
Level Measurement Instruments
Radar, guided wave radar, and DP level transmitters for tanks, vessels, and separators.
Temperature Transmitters & Thermowells
RTD and thermocouple assemblies with headmounted transmitters.
Digital Pressure Gauges & Manometers
Handheld and panel-mount digital gauges for commissioning, calibration and process monitoring. Wet/wet models for liquids and gas.
Pressure Switch/Gauge
Combination DP gauge + setpoint switch for dust collector filter control and HVAC AHUs.
Gas Detectors: Fixed & Portable
LEL, H₂S, O₂ and toxic gas sensors for Zone 1/2. Mandatory on all O&G sites — very high procurement frequency in GCC.
Flow Meters
Coriolis, magnetic, and vortex flow meters for custody transfer and process measurement.
Pressure Transmitters
4-20mA HART and FOUNDATION Fieldbus pressure transmitters.
Application & Solutions
In oil and gas production, refining, and petrochemical processing, field instrumentation forms the sensing layer of every control and safety system. Pressure transmitters monitor separator and vessel operating pressures, feeding real-time data to PLCs and DCS systems for process control and high pressure trip functions. Temperature transmitters protect heat exchangers, fired heaters, and reactors by providing the process variable inputs that safety instrumented systems rely on to initiate safe shutdowns. Guided wave radar and differential pressure level instruments monitor crude oil, produced water, and chemical storage tanks enabling accurate inventory management and overfill prevention. Flow meters measure production rates, utility flows, and chemical dosing quantities across the full process train.
All instrumentation for hazardous area installation is specified with the correct ATEX or IECEx Ex ia certification for Zone 0, Zone 1, or Zone 2. We also supply the complete range of intrinsic safety associated apparatus Zener barriers and galvanic isolators for mounting in safe area marshalling cabinets alongside field instrument terminations.
In water and wastewater treatment facilities, differential pressure transmitters monitor filter loading, electromagnetic flow meters measure dosing and effluent flows, and level instruments manage tank and sump control all feeding into PLC-based SCADA systems for automated plant operation.
For HVAC, building services, and district cooling applications, our instrumentation range includes differential pressure gauges for filter monitoring, duct pressure transmitters for fan speed control, temperature and humidity sensors for air handling unit regulation, and variable area flow meters for chilled water circuit balancing.
Fixed and portable gas detection systems for LEL, H₂S, O₂, and toxic gas monitoring complete the offering — a mandatory procurement category for every Oil & Gas, Petrochemical, and Marine facility operating under UAE and GCC safety regulations.
As a single-source instrumentation procurement partner, ConnectSys can manage your complete Instrument Index from specification review and datasheet approval through to supply, tagging, calibration documentation, and site delivery.
