Slimline P/T

Pressure/Temperature Sensor


Product Features-

* Excellent stability
* ± 0.25% FS accuracy both pressure and temperature
* High integrity and reliability
* Fully welded 316 stainless with one-year corrosion warranty
* Output: 2- 2-wire, 4-20mA loops
* Repairable/replaceable sensor/cable assembly
* Standard TPE alloy or Extra Duty “stainless steel” cable

The Dynotek Slimline Submersible Pressure/Temperature Transducer provides accurate downhole pressure and temperature measurements for geothermal, coal bed methane, conventional gas, and other thermally sensitive wells. The pressure transducer is a sealed gauge configuration, giving maximum protection from water intrusion for long life. Unlike vented gauge transducers, the Slimline is hermetically sealed, with no open air path to introduce moisture into the delicate electronics of the sensor. The temperature sensor is packaged internally, and reports temperature though a stable 4-20 mA current loop.

Slimline is only 0.69 inches in diameter, making it easy to insert into sounding tubes, an access hole in a pump base, or into one-inch diameter stilling well tubing.

The pressure component of the Slimline P/P sensor is repairable. If the cable or watertight connection are compromised during use, the pressure sensor generally can be reconnected to the same cable or a new one. The temperature component is generally nott recoverable. If the sensor fails while under the one-year warranty, a new sensor will be provided and connected to the customer’s cable.
