Pressure Sensor
VORTORQ® has 39 years of experience in pressure sensor manufacturing. We adopt one of the most advanced technologies in the sensor industry; sputtering film technology and Micron-fused technology.
A pressure sensor is an instrument consisting of a pressure-sensitive element used to determine the actual pressure applied to the sensor; the information is converted into an output signal. Pressure is the force exerted by liquid or gas on the surface, usually measured in power units per unit of surface area. The standard units are Pascal (PA), bar (bar), N / mm2, or pound / square inch (PSI).9
VTM530 Pressure Transmitter
Over view
The VTM530 pressure transmitter use strain gauges bonded on 17-4PH stainless steel (SS) diaphragm based on micro-fused glass frit technology. The strain gauges with uniform resistance are obtained by growing an epi-silicon layer on a single crystal silicon wafer using epitaxial deposition technique rather than conventional photolithography and etching techniques.
The inorganic micro-fused glass frits are used as the bonding material between the strain gauges and the 17-4PH SS diaphragm. Compared to organic adhesives, the glass frits bonding material can minimize the hysteresis error in high-temperature applications and improve the mechanical properties of semiconductor strain gauge-based pressure transducers. u

VTMH530 Hydrogen Pressure Sensor
Over view
The VTMH530 features VORTORQ’s proprietary micro-fused technology pressure sensing element. The thread, hex, and diaphragm are machined from one piece of 316L SS, eliminating the risks associated with other sensor technologies, including media compatibility, weld failures, and contamination through an oil-filled cavity. The MP5300 pressure sensors passed all tests, including media compatibility, aging, corrosion resistance, endurance testing, pressure cycling, leakage testing, isolation, noise compatibility, and hydraulic strength. The thick diaphragm of the 900 bar (13,053.4 PSI) pressure sensors held the 1,800 bar burst pressure test and continued to operate above 2,400 bar until the O-ring was extruded.
Application
TheVTMH530 is constructed to meet the environmental conditions associated with hydrogen pressure measurements. Each sensor is packaged with a welded stainless steel housing and sealed electrical connection. The sixty (60) pressure sensors test batch was subjected to various shock, vibration, and environmental tests. In addition, the sensors withstood thermal, mechanical, and drop tests. Environmental testing included humidity storage and cycling, chemical testing, water spray, salt fog, storage temperature, and dust.

VTMP710 Flush Diaphragm Pressure Sensor
Over view
This flush diaphragm pressure sensor series adopts a state-of-the-art technical solution with a very sturdy flush steel measuring diaphragm. This technology makes the product unique and suitable for pressure measurement in very dense and aggressive fluids and pastes.
A flush diaphragm is a type of diaphragm which is completely open and exposed to the pressure media and level or slightly recessed to the surrounding surfaces when installed.
VTMP710 offers an extensive range of transducers for pressure measurement in all industrial applications. In addition, models are available for special and high-precision applications, also for use in particularly heavy duty and demanding environments, such as mobile vehicles.
In addition, this series introduces new membranes miniaturized sizes which are the smallest of their kind on the market.
Description
VTMP710 with its monolithic measuring diaphragm structure, is the ideal product for very high-pressure measurements, up to 5000 bar, even with high dynamic push-button pressure.
Pressure transmitters and transducers with open flush diaphragms suitable for use with highly viscous media such as plastics, paper pulp, bitumen, sewage, paint and adhesives..
A pressure sensing device with a flush diaphragm is installed by either clamping to a flange ring around the outer diameter of the diaphragm or using a thread which has a large enough diameter to incorporate the diaphragm at the tip of the thread.
