Pressure Transmitter
Open up a hydraulic press, a chiller or a water pump, and you’ll usually find a small steel cylinder screwed in somewhere, with a cable trailing out of it. It looks unremarkable, but it’s listening to the system all day long. When the pressure rises, falls or starts to wander, that little cylinder is the first to know, and it passes the news on as an electrical signal.
That cylinder is a pressure transmitter, and the QYB100 is the one we offer at Levtron Instrument Pvt. Ltd. in Pune. It’s a piezoresistive transmitter in a stainless steel housing, built to fit most industrial pressure jobs. Whether you’re watching a pump, a valve or a refrigeration line, it turns pressure into a clean signal your PLC or panel can use.
What Is a Pressure Transmitter?
A pressure transmitter is a sensor that measures the pressure of a liquid or gas and converts it into a standard electrical output. Instead of reading a dial by eye, your control system receives a steady signal and can log it, display it or act on it.
Inside the QYB100 is a silicon piezoresistive sensing element. When pressure pushes on the stainless steel diaphragm, silicone oil carries that force to the sensor, whose electrical resistance changes slightly. The electronics turn that change into a signal such as 4-20 mA or 0-10 V.
Why Choose Pressure Transmitters From Levtron?
A transmitter works in the middle of your process for years, so it’s worth knowing who stands behind it. Here’s what buyers tend to like about working with us:
- Wide pressure choice: Ranges run from 100 mbar up to 600 bar, and up to 1000 bar, in gauge, absolute and sealed gauge types.
- Two accuracy options: You can pick ±0.25% FSO or ±0.5% FSO, depending on what your process needs and what you want to spend.
- CE certified: The QYB100 is CE certified, with a calibrated and temperature-compensated design.
- Built to order: Range, output, electrical connection and process connection are chosen from a clear ordering code, with custom options on request.
- Round-the-clock support: Our team provides remote support at any hour, so a question doesn’t wait until Monday.
Applications of Pressure Transmitters
Any plant that moves or stores liquids and gases can use a pressure transmitter. Here are the common cases:
- Process control systems: Pressure signals help control reactors, lines and utilities. The standard output fits straight into PLCs and panels.
- Refrigeration and HVAC: Chillers and compressors need pressure feedback to run efficiently. The transmitter helps control the system and spot faults early.
- Hydraulic systems and valves: Presses, lifts and valves depend on steady hydraulic pressure. A transmitter watches the circuit and helps prevent damage from overpressure.
- Machine building: Machine makers build transmitters into their equipment to monitor and control pressure. The compact body is easy to fit into tight designs.
- Pumps and compressors: Pumps and compressors need pressure monitoring to protect them from running outside safe limits. The signal can drive alarms and shutdowns.
- Level measurement and test equipment: Pressure at the bottom of a tank shows the height of liquid above it. Test benches and labs also rely on dependable pressure readings.
Wherever fluid is pumped, stored or compressed, a pressure transmitter keeps the process under watch.
Salient Features of Pressure Transmitters
Here’s what you can expect from the Levtron QYB100:
- Silicon piezoresistive sensor: A high-quality silicon sensor sits in a stainless steel housing, with a 316L stainless steel diaphragm. It suits all media compatible with 316L stainless steel.
- Accuracy and stability: Accuracy is typically 0.25% FSO, and long-term stability is typically ±0.2% FSO per year. Readings stay dependable without frequent recalibration.
- Choice of output signals: Outputs include 4-20 mA, 0-5 V, 1-5 V, 0-10 V and 0.5-4.5 V ratiometric. The 4-20 mA version runs on a 12 to 36 V DC supply.
- Rugged and protected: IP65 protection is standard, with IP68 on the cable outlet. It’s rated for 10 g vibration and 100 g shock, and works from -20°C to +85°C.
- Many connection options: Electrical options include DIN43650, cable outlet and M12x1. Process connections include G1/4, G1/2, M20x1.5 and 1/4 NPT.
All of this adds up to a transmitter that’s simple to fit and doesn’t need constant attention.
Benefits of Pressure Transmitters
Here’s what changes once you add reliable pressure monitoring to your plant:
- Problems show up early: A steady signal reveals drops and spikes straight away. You can act before a small issue turns into downtime.
- Better equipment protection: The transmitter handles overpressure of up to 1.5 times full scale. Alarms catch dangerous conditions in time and protect pumps, valves and pipework.
- Remote monitoring: The signal travels to your control room, so nobody has to walk the plant to read a gauge. Your team saves time and avoids risky areas.
- Stable readings over time: Calibrated, temperature-compensated sensing keeps readings consistent through the year. That means fewer recalibrations and fewer surprises.
- Easy integration: Standard outputs and connections fit most control systems and installations. Setup is quick and your operators learn to trust the signal.
For most plants the biggest gain is simple: you stop finding out about pressure problems the hard way.
