Description
Designed for outdoor use. Palmer's hermetically sealed multi-speed battery operated chart drives operate reliably even in wet and dirty environments. Freezer tested to -40°F, these drives will withstand extreme temperatures. The highly adaptable design will fit any chart recorder, and makes exchange in the field a snap. 12 selectable speeds: 30 min., 60 min., 2 hr., 4 hr., 6 hr., 8 hr., 12 hr., 24 hr., 48 hr., 3 day, 4 day, or 7 day recording intervals. No OFF.
The speed dial on the front of the case allows field selectable recording intervals. Our multi-speed battery operated chart drives are rated intrinsically safe, which makes them ideal for use by gas utility companies and in other situations where hazardous or combustible materials are present. A pulsating LED indicator behind the dial shows that the battery is charged and that the unit is operating. Available with 5/8 inch long drive shaft or 1.25 inch long drive shaft.
No Axial or Angular Backlash means charts don't shift. Closed construction case protects all moving parts. Separate battery compartment prevents the drive from corrosion damage.
UL Listed: Class I, Groups C and D, Intrinsically Safe.
