Emerson EPRO EZ1900-040 Pressure Transmitter

The EPRO EZ1900-040 appears to be a  pressure transmitter manufactured by EPRO Messtechnik GmbH. 

Function:

Measures pressure in a gas or liquid and converts it into a proportional electrical signal (usually 4-20mA current loop).
This signal is then transmitted to a control system for monitoring and process control purposes.

Specifications:

• Pressure Range: The specific pressure range it can measure (e.g., 0-10 bar, -5 to 5 psi).
  
• Output Signal: Likely outputs a 4-20mA current loop signal corresponding to the measured pressure.
  
• Accuracy: The accuracy of the pressure measurement (e.g., ±0.5% of full scale).
  Process Connection: The type of fitting used to connect the transmitter to the process (e.g., NPT, G1/4).
  
• Electrical Connection: The type of electrical connector used for power and signal output (e.g., cable with screw terminals).

Features:

• Compact Design: EPRO is known for its compact pressure transmitters, making them suitable for applications with limited space.
  
• Piezoresistive Sensor Technology: This technology offers good accuracy and reliability for pressure measurement.
  
• Stainless Steel Construction: Likely made from corrosion-resistant stainless steel for harsh industrial environments.
  
• Temperature Compensation: May have internal temperature compensation to ensure accurate readings across varying ambient temperatures.

Applications:

Process Control and Monitoring: The EPRO EZ1900-040 is used in various industrial automation and process control applications to monitor pressure in:

• Hydraulic and pneumatic systems.
  
• Pipelines for liquids and gases.
  
• Chemical processing plants.
  
• Food and beverage production.
  
• Power generation plants.
