STG19 High Precision Micro Pressure Transmitter

The STG19 Micro Pressure Transmitter utilizes a titanium alloy sintered sensing element, combined with laser trimming and computer-based automatic testing, to achieve high-precision micro pressure measurement over a wide temperature range. It can measure both absolute and differential micro pressures, offering high resolution and strong anti-interference performance. STG19 is ideal for aerospace, precision testing, bioengineering, and various analytical instruments. The signal processing circuit is housed in a corrosion-resistant 304 stainless steel case, supporting multiple output signals (4-20mA, 0-5V, 0-10V, mV, Modbus-485RTU) and versatile pressure interfaces (G1/2, G1/4, M20*1.5, or custom), meeting diverse industrial requirements. With high reliability and long-term stability (<0.05% F.S/year), the STG19 can withstand overpressure up to 1000KPa and a burst pressure over 1600KPa. Its temperature compensation range is -30~+85°C, and operating temperature is -30~+125°C, ensuring stable performance in demanding environments. Vibration and shock resistance comply with IEC standards, and EMC anti-interference requirements are met, making it suitable for military and high-precision applications. Compatible with gases or liquids that work with 316 stainless steel, the STG19 is an ideal solution for precise micro pressure measurement.
