Media-isolated piezoresistive silicon core with welded SS316L wetted parts and Hirschmann DIN 43650-A connector.
Where Our Sensors Work
We present our sensing solutions around real operating environments — water, power, transport, equipment, and new energy — because sensors must survive actual process conditions, not just laboratory spec sheets.
Water & Irrigation
From variable speed booster pumps to deep agricultural borewells and municipal water filtration, ACT sensors handle water hammer, wide line pressure swings, and long-term submersion.
Compressed Air & Gas
Handling severe mechanical vibration and hot oil-mist environments in rotary screw compressors, plus trace moisture dew point sensing downstream of desiccant dryers.
Railways & Transportation
Engineered and certified to EN 50155 & EN 61373 for extreme track vibration, high voltage transient immunity, and critical pneumatic brake monitoring across locomotives and EMUs.
Automotive & Mobility
Compact 5V ratiometric and analog transmitters engineered for vehicle test cells, diesel common rail monitoring, automotive air conditioning loops, and mobile construction machinery.
Industrial Equipment
Heavy-duty pressure measurement and threshold switching for hydraulic power packs, injection molding machines, commercial chillers, and industrial autoclaves.
Energy & New Applications
All-welded SS316L monolithic diaphragm sensors designed for high-purity hydrogen gas, electrolyzer water loops, fuel cell test benches, and sustainable energy skids.
Understand the Sensor Family Before the Model Code
We organize our measurement solutions by sensor architecture, operating characteristics, and industrial applications — so you can select the right technology for your exact operating conditions.
Flush-Mount Diaphragm Transmitters
Zero cavity dead-volume for viscous, paste, and hygienic fluids
Designed with an exposed front-flush stainless steel diaphragm that eliminates dead space, preventing media buildup, crystallization, and bacterial entrapment during CIP washdown.
Food & beverage processing, syrups, pastes, dairy
Compact & OEM Series Transmitters
Cost-optimized, water-hammer resistant for series machinery
Rugged, high-volume sensor architecture engineered for equipment builders. Features built-in snubbers/dampers to absorb water hammer and rapid pressure pulsations in pumps and mobile systems.
Constant-pressure VFD water booster pumps
Industrial Heavy-Duty Pressure Transmitters
Wide measuring spans with high overload resistance for harsh plant lines
Solid-state piezoresistive silicon and foil strain gauge technology built into welded stainless steel bodies for extreme thermal and mechanical duty.
Hydraulic press systems and industrial power units
Electronic Pressure Switches with Display
Local digital readout with dual switching contacts and analog feedback
Combines an on-site digital LED pressure gauge with 2 programmable PNP/relay switching outputs and an analog 4-20mA loop. Enables immediate visual monitoring and automated interlocking.
Hydraulic power pack pressure interlocks & clamping
Submersible Hydrostatic Level Transmitters
Continuous liquid head measurement in deep tanks, wells, and reservoirs
Probe suspended directly into media, measuring hydrostatic column pressure. Built with integrated atmospheric venting capillary inside heavy-duty PUR/PTFE cable for automatic barometric compensation.
Deep agricultural boreholes & tube well monitoring
Differential Pressure Transmitters
Ultra-low micro-pressure & filter delta-P monitoring
Measures pressure differential across two ports using isolated MEMS piezoresistive silicon cores. Essential for verifying filter loading, air duct velocity, and cleanroom positive pressure.
Pharmaceutical cleanroom & isolation room differential
Precision Digital Pressure Gauges
Battery-powered on-site test bench & verification reference
Rugged stainless steel 304 gauges featuring high-resolution 4-digit or 5-digit LCD screens. Ideal for mobile maintenance technicians and field pressure verification.
On-site field inspection and gauge proofing

Inside ACT Sensors: Built & Calibrated in India
No stock renders. No generic illustrations. Take a look inside our assembly, multi-point pressure calibration, and inspection facility at GNP Galaxy, Ambernath (Thane, Maharashtra).
Multi-Point Pressure Calibration Rig
Every sensor batch undergoes individual multi-point verification against traceable reference calibrators before dispatch. We verify zero drift, full-scale span, and thermal offset stability.
Sensor Inspection & Wiring Workbench
Hands-on evaluation of piezoresistive silicon cores, SS316L isolation diaphragms, barometric venting capillaries, and electrical insulation prior to final potting and encapsulation.
Assembly & Final Quality Control
Our Ambernath engineering technicians verify 4–20 mA / 0–10 V loop output stabilization, check Hirschmann / M12 pinouts, and assign serial numbers with factory test certificates.
ISO 9001:2015 Quality Traceability
Operating under an audited ISO 9001:2015 quality framework. Comprehensive Quality Assurance Plans (QAP), factory calibration reports, and batch inspection records provided where required.
