SPX series

Melt pressure sensors series SPX - 2

SPX-2 Series

The SPX-2 series is an intelligent 4-20mA pressure sensor designed for use in hazardous areas and is available with various process and electrical connections. The SPX - 2 series is a robust welded construction. 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. Optional thermocouples or RTD configurations are also available for simultaneous temperature and pressure monitoring at a single connection point.

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.

1490 Panel Indicator

Indicator 1490 is a universal device with one or two configurable alarms, optional linear process variable retransmission, optional pressure sensor power supply, and optional Modbus communication.

UPR 900 Panel Indicator
