SPX series

Melt pressure sensors series SPX-T 3

SPX-T - 3 Series

TSPX-T (Series 3) is an intelligent 4-20 mA series of sensors that includes temperature compensation and Dynisco Innovation - DynaLarity ™. The SPX-T delivers the most powerful sensors in the range. Temperature compensation is based on RTD measurements that compensate for temperature changes that reduce temperature variations and increase accuracy. There is no need to perform a temperature calibration after installing the sensor.

DynaLarity uses an advanced algorithm that will linearize offsets on the sensor. The combined temperature compensation and DynaLarity functions reduce temperature-related deviations by up to 80% and improve accuracy by more than 60% compared to other sensors. Combined temperature sensors are also available (RTD or 4-20mA). HART communication is a standard in this series. SPX 3 series with welded non-removable construction designed for use in potentially explosive atmospheres and other demanding applications.

These amplified transmitters eliminate the need for external signal conditioning. All models can be directly connected to high-level distributed control systems, PLCs, computers, and similar control systems.

Transducer Mounting Hole Cleaning Tool Kit

Installation of transducers into improperly cleaned or sized holes is one of the major causes of damage to these instruments. With this kit, the .312" tip diameter hole, the 45 degree seating surface, and the .451" hole can be cleaned. The kit includes a gauging plug which is used to verify that the hole has been correctly machined and cleaned. M10 and M18 cleaning kits also available.

Transducer Mounting Hole Machining Tool Kit

The Dynisco Transducer Mounting Hole Machining Tool Kit contains all of the necessary drills and taps to prepare a standard 1/2 - 20 UNF transducer mounting hole and the 45 degree seat. All tools included in this kit are made of premium grade, high strength tool steel. Care should be taken in the use of proper speeds and feeds, lubricants, and a method to assure continual alignment of each progressing tool. M10 and M18 kits are also available.

1480 Panel Indicator

1480 is a universal pressure or temperature indicator with one or double configurable alarm as well as optional linear retransmission of the displayed process. Ideal for use in extrusion applications.
