A 19mm standard OEM oil-filled isolated diaphragm pressure core in all 316L stainless steel.
For seawater and chloride rich media, the GS19Ti variant uses a TC4 titanium housing with a TA1 titanium diaphragm, providing strong resistance to chloride corrosion.
A tantalum diaphragm can also be customized for particularly demanding media, while the standard 316L version covers general liquids and gases.
Supports constant current excitation of 1.5mA or constant voltage excitation up to 10V DC, selected by ordering code C (current) or V (voltage)
Working ranges from 0-10kPa up to 100MPa with gauge (G), absolute (A), and sealed gauge (S) pressure types.
Response time under 1ms, pressure cycle life over 100 million cycles tested at 80% full scale, operating and storage temperature from -40 to +125 degrees, and compensated temperature of 0 to 50 degree
Widely used in industrial process control, level measurement, gas and liquid pressure measurement, pressure calibration instruments, pressure switches and hydraulic systems, refrigeration equipment

AI-Powered supplier vetting
SummaryThe supplier is identified as a trading company engaged in sensor, transmitter, and related instrument research, manufacturing, sales, and service. It reports ISO 9001-related certification, TS 16949 and ISO 20000 certifications, CE capability, ERP integration, three production lines, and documented procedures for supplier-service assessment, corrective actions, and complaint handling. It offers 3D design, ODM, and multiple customization models, but reports no new products during the past year, no SDK, and no OEM service for popular brands. Overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero. Financial records are referenced for recent years, but the provided slices do not disclose sufficient non-financial evidence to assess financial credibility. No customer cases are provided.
Supplier typeThe supplier is explicitly classified as a trading company. Its company description states that it conducts research, development, manufacturing, sales, and service for sensors, transmitters, and related instruments.
CertificationsThe supplier reports TS 16949, ISO 9001, and ISO 20000 certifications, along with an ISO 9001:2015 certificate and CE certification capability. These stated certifications provide explicit evidence of formal quality or management-system credentials.
After-Sales capabilityThe supplier reports documented and followed procedures for corrective and preventive actions and customer complaints. However, it has no overseas warehouse, showroom, agent, or branch, and the stated overseas-service country count is zero, indicating documented service processes but limited overseas service infrastructure.
Production capacityThe company describes itself as involved in manufacturing sensors and related instruments and reports operating three production lines. It also provides a stated water-level-sensor output figure, but the overall production scale and broader capacity are not sufficiently detailed for a complete capability assessment.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product customization capability.
Product Q&A
Q:What pressure ranges and pressure types are available for the GS19 series?
A:
Working ranges cover 0-10kPa up to 100MPa. Pressure types offered are G (gauge), A (absolute), and S (sealed gauge). A flush diaphragm variant covers -100kPa to 10MPa for level and viscous media applications. Overload capacity is 1.5 times full scale.
Q:Can the GS19 replace the pressure cores I am currently using?
A:
Yes. The GS19 series is designed with the same dimensions, mounting, and sealing as mainstream global counterparts, so it can be installed as a drop-in replacement in existing transmitter and instrument designs without mechanical or sealing modification. The series is backed by over 30 years of R&D and manufacturing experience.
Q:What is the GS19Ti titanium variant used for?
A:
The GS19Ti variant features a TC4 titanium housing and TA1 titanium diaphragm, which provide strong resistance to chloride corrosion. It is designed for seawater and corrosive media applications such as offshore and marine environments. A tantalum diaphragm can also be customized for particularly demanding media.
Q:How do I choose between constant current and constant voltage excitation?
A:
The GS19 supports two excitation modes: constant current of 1.5mA or constant voltage up to 10V DC, selected by ordering code C (current) or V (voltage). Choose the mode that matches the excitation source of your signal conditioning circuit; both modes deliver a millivolt output to your amplifier input.
Q:What is the output signal and how is the sensor wired?
A:
The output is a millivolt signal: full-scale 35 to 280mV depending on range, typical 80mV and maximum 150mV at the basic configuration. Wiring uses 4-color silicone leads (IN+ red, IN- black, S+ yellow, S- blue), with gold-plated pins available as an option.
