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
