Battery-Powered Self-Contained Pressure Monitoring Solution
Sino-Instrument’s wireless pressure transmitters are extremely efficient,
due to their unique energy management based on an ultra-low-power design.
The wireless signal pressure transmitter of the pressure-sensitive chip,
selected into the patch process, with zero, full-scale compensation,
temperature compensation of high-precision and high stability amplification IC,
will measure the pressure of the medium into 4 ~ 20mA, 0 ~ 5VDC, 0 ~ 10VDC, 0.5 ~ 4.5VDC,
and other standard electrical signals.
Product structure using full-welded structure,
so that the product’s impact resistance, overload capacity,
product sealing performance has been greatly improved,
the maximum product pressure can reach 150MPa.
There are several ways to connect the product process and the electrical connection,
to the maximum to meet the needs of users.

Working Principle of SI2088-W Wireless Pressure Transmitter
The SI2088-W pressure transmitter,
provides a wireless solution for safe operation in tough industrial,
and process applications eliminating the need for hard wiring.
The SI2088-W transmitter can be situated in inaccessible areas,
allowing the operator to monitor at safe distances on site.
No hard wiring means lower installation cost and maintenance.
The unique Silicon-on-Sapphire sensor technology provides outstanding performance
and gives excellent stability over a wide temperature range.
The advanced sensor design consists of a piezoresistive silicon strain gauge circuit,
which is epitaxially grown onto the surface of a sapphire diaphragm,
to form a single crystalline structure.
The sapphire sensor element is then molecularly bonded to a titanium alloy sub-diaphragm.
This enables the sensor to endure higher over-pressures and provides superb corrosion resistance.
The sensor exhibits virtually no hysteresis and excellent long-term stability.
With outstanding insulation properties, the sapphire substrate allows the sensor,
to operate over a very wide temperature range without loss of performance.
Robustly constructed from stainless steel,
the SI2088-W transmitter offers optimum stability and repeatability,
in all industrial and process environments.
The SI2088-W transmitter operates by sending data signals,
by radio telemetry to a receiver which provides a 4-20 mA output signal.
Powered by an internal battery or 8-30 Vdc supply,
the transmitter is capable of sending data signals at distances of up to 500 feet/ 200 meters.
Applications of SI2088-W Wireless Pressure Transmitter
Typical applications include mechanical and civil engineering installations, process plant,
water utilities, petrochemical,
power generation and any application on fluid or gas requiring a stable,
repeatable and accurate pressure measurement at distances on site.
The removal of the large cap at the head of the unit,
allows easy access for zero/span adjustment and re-calibration or for battery replacement.
Standard pressure connection is 1/2” BSP or optionally 1/2” NPT is available. Pressure ranges are from 0-500 mbar to 0-1,500 bar.
