A trusted level switches and level transmitters supplier and manufacturer provides two of the most essential instruments in any industrial process plant. Whether you need a simple ON/OFF alarm or a continuous real-time signal for your control system, the right level instrument ensures process safety, equipment protection, and reliable automation.
Q: When should I use a level switch instead of a level transmitter?
A: Use a level switch when you only need to know if the level has reached a specific high or low point, such as a pump cut-off or overflow alarm. Use a level transmitter when you need a continuous, real-time level reading for process control, operator display, or inventory tracking.
Q: Can one instrument serve as both a switch and a transmitter?
A: Yes. Many modern level transmitters include built-in relay outputs for high and low alarms, combining both continuous measurement and point level switching in a single device, reducing installation cost and panel wiring.
Q: What is SIL 2 certification for level instruments?
A: SIL 2 (Safety Integrity Level 2) certifies that the device can reliably perform a safety function, such as overfill protection, with a very low probability of failure on demand. SIL-rated instruments are mandatory in Safety Instrumented Systems in oil, gas, and chemical plants.
Q: Which technology is best for corrosive chemical applications?
A: Non-contact technologies with no wetted parts are the safest choice for aggressive media. Where probe contact is unavoidable, instruments with PTFE-lined, Hastelloy, or ceramic wetted components provide reliable long-term performance in acid, alkali, and solvent service.
