A gauge pressure transmitter is an essential device widely used in various industries to measure the pressure of fluids—such as liquids, gases, and steam—relative to atmospheric pressure. These transmitters are vital for monitoring and controlling processes, ensuring systems operate safely and efficiently. The following are some of the key features and specifications that highlight the performance and reliability of a typical gauge pressure transmitter.

Key Features

1. High Stability Piezo-resistive Silicon Sensor
   This advanced sensor technology provides excellent stability and accuracy, making it suitable for precise pressure measurements.

2. Pressure Range: 0 to 60 MPa
   The transmitter is capable of measuring a wide range of pressures, allowing it to be used in various applications across industries.

3. High Accuracy: Up to ±0.035%
   This level of accuracy is critical in applications where precise pressure measurement is necessary for efficiency and safety.

4. Reverse Polarity & Surge Protection
   The device includes features designed to protect against electrical issues, ensuring reliable operation even in less-than-ideal conditions.

5. Communication Protocol: HART
   Utilising the HART protocol allows for easy integration with control systems and facilitates the transmission of additional diagnostics and configuration parameters.

6. Certification: ATEX, CE, SIL Certified, NAMUR Compliant
   These certifications demonstrate that the transmitter meets rigorous safety and environmental standards, making it suitable for use in hazardous environments.

Understanding the Lock Feature

After you lock your Rocksensor RP1002 Smart Gauge Pressure Transmitter, the Z and S buttons on the device’s top will become disabled. This feature helps prevent accidental adjustments to the settings, ensuring the transmitter operates under its intended parameters. However, you will need to unlock the transmitter to make any adjustments.

Steps to Unlock the RP1002

To unlock the RP1002 Gauge Pressure Transmitter, follow these straightforward steps:

1. Locate the Z Button: Identify the Z button on the top panel of the transmitter. This button is essential for the unlocking process.

2. Press and Hold: Firmly press and hold the Z button.

3. Timing: You will need to maintain pressure on the button for 30 seconds. It’s important to hold it continuously without interruption, as any release may cancel the process.

4. Monitor the Display: As you hold the button, keep an eye on the display screen. After about 30 seconds, you should see the message “EW” appear on the screen. This indicates that the transmitter is now unlocked.

5. Test the Buttons: Once the eeprom write “EW “ message is visible, you can release the Z button. Test the Z and S buttons to confirm that they are now functional. If they respond as expected, you have successfully unlocked your transmitter.
