SPX - Smart Pressure Sensors for Small Flange Mount Installations Model 2243
The SPX2243 is a smart 4 - 20 mA pressure transmitter designed for use in hazardous locations. The SPX2243 is an all welded construction that features a small diaphragm and a mounting flange for easy installation. Optional thermocouple or RTD configurations are available to provide melt temperature. The SPX2243E has explosion proof approval for Class 1, Division I, Groups A, B, C & D. The explosion proof model employs a conduit fitting. The SPX2243S is ATEX/Intrinsically Safe approved for II 1 G 100a Eex ia IIC, Zones 0 and 1. The intrinsically safe and ATEX models can be supplied with either a conduit fitting or a hermetic 6 pin Bendix connector.

The SPX-T is a smart 4-20mA pressure transmitter that includes Temperature Compensation and DynaLarity™, a Dynisco innovation. The SPX-T delivers the best spec performance in the line. Temperature Compensation is based on a primary RTD measurement that compensates for temperature variations which reduces temperature-related drift and increases accuracy. No need to re-zero for temperature changes after installation. DynaLarity uses an advanced algorithm that linearizes offsets due to process effects on the sensor. Combined Temperature Compensation and DynaLarity reduces temperature-related drift by as much as 80% and improves accuracy by more than 60% over other sensors. Process temperature output is available. HART communication is standard. Explosion proof, Non-incendive and Intrinsically Safe configurations are pending approval. The SPX3391 is an all-welded construction that features a large diaphragm and mounting flange for easier installations.
