Specification No 02130 Rev.07-10

High Pressure, Wide Temperature Range

The 700 Series Linear Position Sensors are designed to operate reliably in extreme

environments such as “down hole” oil well applications at temperatures between -40°

and +300°C and pressures of up to 28,000 psi. Containing a conductive plastic

resistive element, the 700 Series has a longer operating life and resolution than

traditional wire-wound units. Offered in miniature diameters for space-saving

advantages, the 700 Series is also designed to meet a wide variety of interface and

in high temperature and high pressure environments with limited space

mounting requirements making it ideal for applications requiring accurate performance
