SPX-T - High Accuracy Smart Pressure Sensors with Temperature Compensation Model 3291

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.

ACCESSORIES

Rupture Disks / Burst Plugs - BP420 Series

The Model BP420 burst plugs are designed specifically for use in plastic extrusion systems. Burst Plugs (also known as rupture disks) are designed for reliable, emergency relief of excess pressure in a system. The Model BP420 will instantaneously rupture at a specific, predetermined pressure and temperature. Each one piece assembly consists of a 304 stainless steel body with a welded Inconel rupture disk. The disk is flush with the tip of the burst plug with no cavity for product build up. A burst plug may be specified for primary relief in applications where pressure build-up can occur so rapidly that the response time of a relief valve is inadequate,such as in a polymerization reaction vessel. All burst plugs are tested at rated burst pressure and temperature. In addition, markings on the burst plugs are laser engraved and more visible, and each burst plug is labeled and shipped in a protective package.
