MDT series

MDT 420 | 422 | TDT 432 - Melt pressure sensors in a design with a fixed rod, a flexible capillary or a combined design with a temperature sensor.

MDT 420 | 422 | TDT 432

The MDT series signal amplifiers convert the process pressure into an amplified signal for long-distance transmission without interference. All models are available in 4-20 mA, 0-5 VDC and 0-10 VDC, 2-, 3- and 4-wire variants. Many of the features found in the standard Dynisco MDA series have been incorporated into the enhanced MDT series, including the proven strain gauge sensor design for stable operation, including the flexible capillary design. The sensors have an internal digital calibration R-Cal.

All sensors in this series can be configured according to your needs. Contact us, we will be happy to help you.

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

The Dynisco UPR900 is a compact 1/4 DIN process indicator. The UPR900 can display your preferred production process values.
