DatasheetDynisco SPX4352 Pressure Transmitter
The Dynisco SPX4352 is a smart 4…20 mA pressure transmitter for precise pressure measurement in hazardous locations. The transmitter is designed for demanding industrial applications and can be connected directly to distributed control systems, PLCs, computers and other high-level control devices.
The SPX4352 features a 1/2-20 UNF threaded jam nut and is therefore especially suitable for space-restricted installation locations. The loop-powered 4…20 mA output reduces wiring requirements and provides stable signal transmission. Optional HART™ communication is available, allowing configuration and parameter adjustment via a handheld communicator.
The SPX4352 is ATEX / intrinsically safe approved for II 1 G 100a EEx ia IIC, Zones 0 and 1. The series offers pressure ranges from 0…500 psi to 0…30,000 psi and provides an accuracy of ±0.25 % FSO, or ±0.5 % FSO for ranges below 1,500 psi. The standard wetted parts are made of DyMax® coated 15-5 PH stainless steel and are suitable for diaphragm temperatures up to 400 °C.
