If you’re involved in applications such as water management, tank level monitoring, borehole and reservoir measurement, or environmental monitoring, you may be wondering: what is a submersible depth & level pressure transmitter and how does it benefit your operation? At ESI Technology, we specialise in designing and manufacturing high-quality pressure measurement solutions, including submersible transmitters built for demanding environments.

Understanding submersible depth & level pressure transmitters

So, what is a submersible depth & level pressure transmitter? In simple terms, it’s a sensor designed to measure the pressure exerted by a column of liquid above it, which directly relates to the depth or level of that liquid. These transmitters are submerged in the liquid and use pressure data to calculate depth, typically expressed in metres of water gauge (mWG).

Our submersible pressure transmitters at ESI Technology are engineered with precision and reliability in mind. Using advanced piezoresistive sensor technology, our devices offer excellent long-term stability and repeatability. This is critical for continuous monitoring applications, where consistency and accuracy can significantly impact process control and safety.

Key features of ESI Technology submersible transmitters

1. Piezoresistive sensor technology
   The core of our submersible transmitters lies in high-performance piezoresistive sensing elements. These sensors respond to pressure changes by altering their electrical resistance, which provides highly accurate pressure readings over time. At ESI Technology, we integrate this technology to ensure our transmitters deliver stable performance in both short-term and long-term deployments.

2. Stainless steel construction
   Designed for durability, our transmitters are constructed with robust stainless steel housings. This ensures resistance to corrosion, mechanical stress, and harsh environmental conditions often found in industrial and marine applications. Whether you’re monitoring levels in wastewater treatment plants or offshore storage tanks, our devices are built to last.

3. Wide range of pressure capabilities
   ESI Technology offers submersible depth and level transmitters with pressure ranges starting from as low as 0-1 mWG. This allows for precise measurements in shallow water applications such as small tanks or groundwater wells, while also covering deeper or high-pressure scenarios.

4. ATEX and IECEx options for hazardous areas
   For environments where explosive gases or dusts are present, our submersible transmitters are available with ATEX and IECEx approvals. We even offer M1 classification for mining applications, enabling safe operation in some of the most hazardous conditions. Safety is a core part of our design ethos at ESI Technology, and our certifications reflect our commitment to compliance and protection.

5. DNV GL approval for marine applications
   ESI Technology’s submersible transmitters are DNV GL approved, making them ideal for use in marine and offshore installations. This global certification ensures that our devices meet strict safety, quality, and performance standards required in maritime operations.
