Accurate pressure measurement and control play a crucial role in many industrial and environmental systems. ProSense offers a wide range of sensing and control products designed to meet the demands of HVAC, water systems, automation, and pollution control. This guide breaks down ProSense’s core technologies, signal output options, sensor types, and product families to help you find the right solution for your application.
Signal Output Options
ProSense devices provide multiple signal output types to ensure compatibility with various control systems and environments. Choosing the right signal output depends on factors like distance, noise levels, and system complexity.
4–20 mA
This is the industry-standard current signal for pressure transmitters. It remains stable over long cable runs and resists electrical noise, making it ideal for industrial environments where signal integrity is critical.
0–5 V
This voltage output converts the 4–20 mA signal and suits general control systems and long-distance communication. It offers flexibility for integration with many automation platforms.
0–10 V
This higher voltage output is designed for environments with significant electrical noise, such as energy plants, IT facilities, and industrial automation setups. It provides a stronger signal to overcome interference.
RS485 (Modbus RTU)
This digital communication protocol supports remote monitoring and multi-device networks. It enables one-to-many control and long-distance signal acquisition, making it perfect for complex systems requiring centralised data collection.
Sensing Unit Types
ProSense offers several sensor technologies, each with unique advantages depending on the application and environment.
Ceramic Sensor
Known for being economical, stable, and corrosion-resistant. Ceramic sensors are suitable for general industrial use where durability and cost-efficiency are priorities.
Oil-Filled Silicon Sensor
These sensors provide high accuracy and low power consumption. They are ideal for applications requiring precise measurement with minimal energy use.
Capacitive Sensor
Offering a low-cost solution, capacitive sensors draw more power but deliver reliable performance in many standard applications.
Strain Gauge Sensor
Compact in size, strain gauge sensors fit well in limited spaces but are less suited for advanced industrial automation due to their sensitivity and complexity.

Industrial Automation
Accurate pressure data from sensors such as the LFT2700 and LFT2800 enable precise control of pumps, compressors, and chemical processes, reducing downtime and improving product quality.
Environmental Control
Differential pressure transmitters like the LFM108 support pollution control and clean room environments by maintaining strict air quality and pressure standards.
Choosing the Right ProSense Product
Selecting the appropriate LEFOO sensor or transmitter depends on your specific needs:
Identify the medium (liquid, gas, steam, viscous fluid) and operating conditions (pressure range, temperature, corrosiveness).
Determine the signal output compatible with your control system (4–20 mA, voltage, or digital RS485).
Consider the sensor type based on accuracy, power consumption, and environmental resistance.
Match the product category to your application, whether it’s differential pressure measurement or general pressure sensing.
