Submersible Level Sensor MPM316W Series

Introduction

The Submersible Level Sensor MPM316W Series is designed with a high-accuracy and reliable OEM gauge sensor, encased in a durable stainless steel housing. This sensor's top steel cap protects the sensor diaphragm while allowing liquid media to pass through unobstructed. The vented tube within the cable ensures precise atmospheric pressure compensation. Ideal for use in various applications, this transducer is suitable for city water supply and drainage systems, water or oil tanks, hydrology, reservoirs, rivers, and oceans.

Features

• Full Stainless Steel Sealed Construction: Ensures durability and longevity in harsh environments.
• Submersible Measurement: Perfect for monitoring fluid levels in submersible conditions.
• Constant Current Supply: Maintains consistent performance.
• Laser Trimming Compensation: Compensates for zero and span thermal errors, enhancing accuracy.
• High Reliability and Stability: Utilizes a solid piezoresistive pressure cell.
• Water-Proof and Oil-Proof Cable: Ensures longevity and reliability in various environments.

Electrical Connection

The Submersible Level Sensor MPM316W Series features a color-coded cable for easy installation:

• Black: +IN
• Yellow (Green): -IN
• White: -IN (if applicable, otherwise not present)
• Red: +OUT
• Blue: -OUT

Ordering Guide

• Cable Length: A 1.5-meter cable is included free of charge. Additional cable lengths are available for an extra cost.
• Fixed Flange: For details on the dimensions and installation of the F1 fixed flange, refer to the MPM416W/WK/WRK submersible level transmitter datasheet.
• Wiring: If the sensor has four wires and no white wire, the definitions for the remaining wires remain the same.
