Mercury Free Series

ECHO - Melt pressure sensor in various designs.

ECHO (NaK) Series

Dynisco's Echo Series offers quality performance through the use of standard configurations and pressure ranges. Echo pressure transducers are designed to meet customer requirements, provide a combination of economical choice and good performance for extrusion applications, while providing ± 0.2% repeatability when measuring process pressures. Echo sensors are the ideal choice for all processes and applications requiring measurement for optimized control.
Dynisco has been manufacturing pressure sensors for more than 60 years. The entire range is backed by a two-year full warranty. The membrane of ECHO sensors is coated with titanium, aluminum, nitride, already in the standard version, which offers better performance than less effective coating of aluminum titanium.
Dynisco technology is very popular with all OEMs and end users around the world. The Echo series is available with 3.33mV / V, 4-20mA, 0-5VDC or
0-10VDC outputs designed to work with most industrial controls. In addition to measuring melt pressure, the Echo series offers optional melt temperature measurement with J, K or RTD thermocouples. The Echo series is equipped with a 1 / 2-20 UNF or M18 thread for mounting in standard mounting holes. Additional mounting configurations are available.

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.
