Product Description
silicon piezoresistive pressure core
The HM1906 pressure sensor adopts a silicon piezoresistive sensor chip with good consistency and strong stability, and is made by the stainless steel corrugated membrane isolation oil filling process; Secondly, the circuit uses pure analog signals and has high sensitivity output. It has advantages such as fast response time, low signal noise, strong anti-interference ability, high reliability, and low cost.
At the same time, the core comes with an NTC temperature sensor, which allows users to directly measure the temperature and use it as temperature compensation for pressure sensors.
Function and Features
Pure analog signal with low noise.
High sensitivity (can reach 141 ± 5mV at 25 ºC and 10bar).
Suitable for measuring media compatible with copper(suitable sealing rings need to be selected).
High reliability, high stability, high consistency, and a service life generally exceeding 5 years.
Compact size.

Boundary dimensions and pin definitions
The measuring medium cannot be frozen;
During installation, avoid scratching the O-ring seal;
During installation, the direction of the pressure inlet should face downwards as much as possible to prevent impurities from settling in the medium and blocking the pressure inlet;
The power supply needs to be filtered to prevent damage to this product caused by instantaneous high currents;
If there are obvious surges in the product's operating environment, it is necessary to add protective circuits such as TVS tubes;
Avoid falling, hitting, and puncturing hard objects;
Avoid product exposure to water and strictly prohibit water immersion;
It is strictly prohibited to disassemble the casing to avoid product damage.
Use of media beyond regulations;
Exceeding the specified power supply voltage for use;
Use beyond the specified temperature range;
Use beyond the specified pressure range;
Severe deformation or damage to the isolation membrane caused by improper operation;
Force majeure, such as product damage caused by lightning strikes, etc;
Other product damage caused by failure to use in accordance with the requirements of this specification.
