The MTM3000 Series miniature submersible transmitter from PMC Engineering is designed for depth and level measurements of groundwater, wastewater and seawater where space is limited. Pressure ranges from 0–10 to 0–500 psi. Operating temperature is 25 to 125 degrees F. The 0.39-inch titanium housing offers high performance in very small areas, such as 1/2-inch monitoring wells, stand pipes and bore holes. The highly developed piezoresistive sensing technology provides high accuracy of 0.1 percent and long-term stability of better than 0.1 percent per year. The technology also provides a high overpressure of at least three times the rated range without any degradation of sensor performance. When used with the MP11 moisture protection option, the user can expect maintenance-free operation for an extended period of time, typically more than 10 years. 203/792-8686;
