171 SPT – Smart Pressure Transmitter

SBEM’s Smart Pressure Transmitter 171 SPT leverages advanced monocrystalline silicon sensing technology to deliver highly accurate and reliable pressure measurements essential for global industrial applications. Designed for water systems and other liquid media, the 171 SPT supports gauge and absolute pressure types with measuring ranges from 0 to 30 bar and accuracy options as fine as ±0.1% of full scale. The transmitter offers flexible output choices including 4-20 mA, HART communication, and RS485 protocols, enabling seamless integration into modern process control systems. Its robust SS316L stainless steel housing and diaphragm ensure durability, while IP65 and IP68 protection ratings guarantee resistance against dust and water ingress. Featuring easy configuration through HART Server, overpressure protection up to 1.5 times the range, and burst pressure tolerance of twice the range, the 171 SPT is ideal for precise, stable pressure monitoring in diverse industrial environments worldwide.
