The Dynisco 4622SA00B21DPDDBAAZZ is a specific model of a smart industrial pressure transmitter designed for melt pressure measurement. This device is part of Dynisco's SPX4622 series, which is known for its high accuracy and suitability for use in hazardous locations, particularly in the plastics and polymer processing industries.
The long part number signifies a precise configuration. Here's a breakdown of what each section indicates:
4622: This is the base model number, identifying it as a SPX4622 series pressure transmitter with a 4-20mA output and ±0.5% combined error accuracy.
S: Denotes the safety approval. "S" indicates ATEX/Intrinsically Safe approval for hazardous environments.
A: Refers to the diaphragm material. "A" means the diaphragm is DyMax® coated 15-5 PH SST (stainless steel), which provides durability and resistance to abrasion.
00: Specifies the mounting connection. "00" corresponds to a standard 1/2-20 UNF mounting thread.
B: Indicates the pressure units and is paired with the following two digits. "B" means Bar.
21: Represents the pressure range. A "21" paired with "B" indicates a range of 350 Bar.
DP: Defines the rigid stem length. "DP" means the stem is 9 inches (23 cm) long.
DD: Specifies the flexible capillary length, which is 18 inches (46 cm) long.
AA: Refers to the electrical connection. "AA" indicates a PT02A-10-6P connector.
ZZ: Specifies that there is no thermocouple or RTD for temperature measurement on this unit.
The 4622SA00B21DPDDBAAZZ pressure transmitter is built for demanding environments. Its key features include:
High Accuracy and Repeatability: With a combined error of ±0.5% FSO and repeatability of ±0.1% FSO, it provides precise and consistent pressure measurements.
Durable and Rugged Design: The DyMax® coated diaphragm and all-welded construction make it resistant to the high temperatures and corrosive materials often found in polymer processing. The flexible stem isolates the electronics from the high process temperatures.
4-20mA Output with HART™: The standard 4-20mA loop-powered output is compatible with most industrial control systems (PLCs, DCS), and its HART™ protocol allows for remote configuration, diagnostics, and calibration.
Hazardous Location Approval: The "S" designation means it is intrinsically safe, making it suitable for use in areas where explosive gases may be present.
This specific model is commonly used in plastics and polymer extrusion processes where monitoring the pressure of molten plastic is critical for maintaining product quality and process stability.
