Frequently Asked Questions (FAQ)
Q1: What is the main difference between gauge, absolute, and differential pressure transmitters?
A: Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure relative to a perfect vacuum. Differential pressure transmitters measure the difference between two applied pressures. The correct type depends entirely on your application's reference point requirements.
Q2: Can these transmitters be used with aggressive or corrosive media?
A: Yes, a key advantage is material flexibility. The wetted parts (the sensor and process connection) can often be specified in special alloys like Hastelloy C-276 or Monel to provide excellent corrosion resistance for challenging fluids like acids, caustics, or seawater.
Q3: How is the output signal typically used in a control system?
A: The standard 4-20 mA analog signal is proportional to the measured pressure range. This signal is wired directly to a PLC (Programmable Logic Controller), DCS (Distributed Control System), or a data acquisition device, which then uses the value for process monitoring, control loops, or alarm generation.
Q4: What does "HART" communication enable?
A: HART (Highway Addressable Remote Transducer) is a digital communication protocol that is superimposed on the standard 4-20 mA signal. It allows for remote configuration, calibration, and diagnostics using a handheld communicator or software from the control room without interrupting the analog signal, greatly simplifying maintenance.
Q5: What is the typical lead time for delivery?
A: Lead times can vary based on model, specific configuration, and quantity. Standard models may have shorter lead times, while customized units with special materials or calibrations may require more time. We provide estimated lead times with every quotation to help with your planning.
Q6: Do you provide calibration certificates with the transmitters?
A: Yes, calibration certificates are typically available. Standard units often come with a factory calibration certificate. For critical applications, traceable calibration to international standards can be provided as an optional service to ensure measurement integrity from the start.
Q7: How do I select the right pressure range for my application?
A: The ideal operating range should be within 50% to 80% of the transmitter's maximum rated pressure for optimal accuracy and longevity. It's important to consider not just the normal operating pressure but also potential overpressure conditions (pressure spikes) and the static pressure in the system for differential pressure applications.
Q8: What kind of technical support do you offer after the sale?
A: Our support includes assistance with installation guidance, troubleshooting, and sourcing replacement parts if needed. As a trading company with extensive experience, we leverage our strong relationships with manufacturers and our global network to provide effective post-sales support for our clients worldwide.
