Industrial Transmitters
What is a Pressure Transmitter?
A pressure transmitter is a device used to measure the pressure of gases or liquids and convert that pressure into an electrical signal that can be read and interpreted by control systems or monitoring equipment. These devices are commonly used in industrial applications such as process control, automation, and fluid monitoring.Activites include:
- Sensing Pressure: It detects pressure using a sensor element (like a piezoresistive or capacitive sensor).
- Signal Conversion: Converts the mechanical pressure into a standardized electrical output (e.g., 4–20 mA, 0–10 V).
- Output Transmission: Sends the signal to a control system (like a PLC or DCS) for monitoring or control.
- Explosion-proof: Certified for hazardous areas (FM, CSA, ATEX)
- Output Signals: 4–20 mA (2-wire) or 1–5 V (3-wire low power)
- Ingress Protection: IP67 / NEMA 4X
- Accuracy: ≤ 0.25% full scale
- Temperature Compensation: Ensures stability in fluctuating environments
- High Durability: Resistant to vibration, pressure spikes, and moisture
