For forklift trucks, telehandlers, and other logistical vehicles, the trend is moving toward more power in a smaller installation space and Rexroth supports this development with its PR4 series 10 pressure sensors. In implement hydraulics and travel drives they cover measuring ranges of up to 600 bar (8702 psi) with a length of 55 mm (2.16 in). The new generation of robust and precise pressure sensors can be used universally in open and closed hydraulic circuits and deliver decisive information for energy-efficient power control. Approved for an ambient temperature range of -40 to 100°C (-40 to 212°F), the sensors can withstand pressure peaks of more than 130% of the nominal pressure; in the version for the highest pressure stage they can momentarily withstand up to 800 bar (11,603 psi). According to Rexroth, the sensors can be easily installed using a socket wrench with a tightening torque of up to 45 n·m (33 lb·ft). For more information, visit www.boschrexroth.com .
