STG17 Explosion-Proof Pressure Transmitter

The STG17 Explosion-Proof Pressure Transmitter features a fully welded housing and digital circuit temperature compensation for high precision and excellent linearity. It is ideal for automated liquid pressure measurement and control in hydraulic systems, oilfields, mines, chemical plants, and natural gas applications. Corrosion-resistant and compatible with 316L media, the transmitter provides protection against reverse polarity, overcurrent, overvoltage, and electromagnetic interference. Pressure range up to 700Bar with accuracy options of ±0.1% to ±0.5% F.S, 4-20mA output, and 12V/24VDC supply. The explosion-proof design complies with GB3836.1 and GB3836.4 standards and features IP67 protection, vibration and shock resistance, and a 304 stainless steel housing. Connections available in 1/4NPT, 1/2NPT, or custom. STG17 is the perfect choice for nuclear power, petrochemical, mining, metallurgy, and other automated liquid pressure control systems.
