The Dynisco 2281SDDCA4B30B is a specific model of a smart industrial pressure transmitter from Dynisco's SPX2281 series. This type of sensor is designed for accurate and reliable pressure measurement in various industrial and hazardous locations.
Here's a breakdown of what the model number signifies and its key specifications:
The part number 2281SDDCA4B30B follows a specific code to define the product's features:
2281: Refers to the SPX2281 series, a smart industrial pressure transmitter. The '2281' specifically indicates a high-accuracy model with a combined error of ±0.25% FSO (Full Scale Output).
S: Indicates Sealed pressure reference. This means the transducer measures pressure relative to a sealed, internal vacuum.
D: Refers to the pressure units, which are in Bar.
D: This character, along with the previous 'D', represents the pressure range. A 'D' in this position means the pressure range is 300 Bar.
C: Specifies the electrical connection, which is a conduit with 42" leads.
A4: Denotes the pressure port fitting. 'A4' specifically corresponds to a 1/4-18 NPTF male thread.
B: Indicates the temperature sensor is not included.
30B: This is likely an additional code for a custom or specific configuration.
The Dynisco 2281 series is known for its robust and precise performance. Key features of this model include:
Output Signal: A 4-20mA loop-powered output, which is a standard for industrial process control, allowing for long-distance signal transmission without significant loss.
High Accuracy: The ±0.25% combined error makes it suitable for applications that require precise and repeatable measurements.
Durable Construction: It features an all-welded construction for enhanced durability and is suitable for use in hazardous locations. The standard wetted part material is Dymax® coated 15-5 PH SST, which is highly resistant to abrasion.
HART™ Communication: The "smart" designation means it supports HART protocol, allowing for remote configuration, calibration, and diagnostics using a HART communicator or software.
Pressure and Temperature Ratings: It can handle high process temperatures and is designed to operate within a wide range of ambient temperatures.
Approvals: The series has various certifications, including CE, ATEX, and FM Explosion Proof approvals, making it suitable for a range of demanding and regulated environments.
In summary, the Dynisco 2281SDDCA4B30B is a high-accuracy, rugged, and reliable smart pressure transmitter designed for precise pressure measurement in industrial applications, particularly those requiring a sealed pressure reference, a 300 Bar range, and specific electrical and process connections.
