20mm diameter with 1-5 volt output

I’m looking for a submersible borehole pressure sensor with a body diameter of no more than 20 mm with a voltage o/p of 1 to 5volts?

We would suggest the LMK306 (17mm dia) which has a 4-20mA series loop output. You can easily convert the 4-20mA to a 1-5Vdc output with a series resistor.

Water well to 75m depth limited to ∅20mm

We are looking for a pressure level sensor for installation in a water well , to a depth of 75 meters with a 4-20mA output, and the diameter dimension must be less than 20 mm?

We would suggest the LMK306 for your application which has a diameter of 17mm and is designed to be lowered into water wells.
