PT303 Pressure Transmitter

Trouble Free Operation

Rigid stem pressure transducers are very easy to install in the mounting hole of the production line. The problem occurs when the sensor is used incorrectly. This transducer can never be used in a vertical installation without thoroughly insulating of the transducer head. The electronics contained in the sensor would be highly exposed to radiant heat from the line and would cause early damage or displacement of measurement values. Therefore, if you are unsure of the correct installation always contact our technicians. If the sensor is repeatedly damaged it is not a defect in the sensor, but due to incorrect use or inappropriate configuration. We are able to solve these problems and offer you the ideal solution for your application.

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. Optional secondary input for displaying the temperature or pressure of the polymer melt all in one place. The secondary input can be a strain gauge to measure the differential pressure in the process. The UPR900 contains two standard assigned alarms with the option to add a third alarm.

ATC990 Process Controller

The ATC 990 series controller is a time-tested product that has received a new design and new functions. Compared to classic features such as pressure, temperature and alarm setting options, these new models are enhanced with the ability to monitor and record parameters to a USB drive, the undeniable advantage is the large display and interactive environment when setting up the controller.

PPS1210 calibration pump

The PPS1210 pressure calibration pump with heated pressure port enables fast and accurate inspection of melt pressure sensors directly in the laboratory or directly in the factory. Thanks to its compact dimensions, it is easily portable.
