Pressure Transducers

Submersible Level Transmitter measures static pressure of the liquid proportional to the level depth using highperformance piezoresistive silicon chip as the measuring element. The result is converted to standard current or voltagesignal output through signal conditioning circuit, establishing the linear corresponding relation between the output signaland liquid depth to complete the measurement of the liquid depth. The product has advantages of high precision andsmall volume. Submerse it directly into liquid, the height between the end of the transmitter to the liquid level ismeasured easily. The product has passed long-term aging and stability screening with stable and reliable performanceand can be used in harsh outdoor environment. It is applicable to the measurement and control of the liquid level in thepetroleum, chemical industry, power plant, urban water supply and hydrological exploration fields.

Pressure Transmitters for Hydrogen Compatible ApplicationsThe piezoresistive stainless-steel measuring cell has expecially been adapted to the chemical and physcial properties of hydrogen. The entire sensor consists for a single piece, which is designed to prevent embrittlement of the metal surface by ionized hydrogen. It is also absolutely vacuum-tight and elastomer-free Leaks caused by material fatigue on internal seals are thus eliminated from the outset. It has no disturbing pressure transfer fluid and no large pressurized surfaces. The membrane is of a very robust design.

The link-in to the connection pins is made by wedge-wedge bonding and is therefore absolutely stable even at low temperatures, or for shocks or vibrations. The measruing bridge evaluates via a mixed singal ASIC. The SPT-H2 can also be used for application where EC79 certification are important
