High Temperature Piezometer (Vibrating Wire)
he 4500HT Series High Temperature Piezometers are designed for monitoring downhole pressures and temperatures in oil recovery systems and geothermal applications, where the temperature may be as high as 250°C. These sensors are supplied with either mineral insulated cables, or with tubular encapsulated cables (TEC) both of which are sheathed inside a stainless steel tube.
