Adapters Button Seal

Process adapters are an accessory to all pressure and temperature sensors, allowing a 1 / 2-20 UNF (Unified National Fine nt) melt pressure sensor to be installed in the mounting port using a flange. The use of the flange is compatible with all sensors of the given dimensions and all manufacturers. Each adapter and sealing elements are made to order depending on the dimensions and mounting port. Flange extensions are available as one-piece constructions or detachable threaded connections. The design of the flange is specific to the one used and depends on the dimensions, thickness and diameter of the mounting screws.

Adaptation of any 1 / 2-20 UNF pressure sensor to the process flange adapter
Can be used with all Dynisco sensors

The flanges can be supplied in one piece, with a thread or a combination of thread and weld

FCR-R - Rheometer

Specifically designed for the synthetic fiber production industry, the Dynisco FCR-R series can be configured to measure a range of apparent shear viscosities, dual melt flow rate, simultaneous melt flow rate and extensional viscosities using the Cogswell Equations. The FCR-R system consists of two parts: a rheometer head and a rheometer control unit (RCU). The rheometer head is connected directly to the process which samples, conditions, and measures the melt viscosity of the molten resin through two separate dies. The RCU controls the rheometer test parameters (temperature, pressure and rate) and takes in data from the measurement head as well as provides outputs of computed results.

On-line apparent viscosities at a wide shear rate range

Unique double capillary design with return current

On-line measurement of polymer elongation properties

Data exchange via analog and digital inputs / outputs

Easy calibration

The Graduated Retractable Melt Thermocouple (GRMT) is used to measure temperatures inside the polymer melt stream. The depth of immersion of the junction into the hot melt stream can be varied from zero to mid-stream during maximum flow and pressure conditions, without removing the sensor from the adapter. Using the graduations on the stem of the temperature sensor allows the user to choose and monitor the specific depth at which the junction is in the melt stream.
