Description

Palmer Circular Chart Recorders are durable, fully mechanical units with a low maintenance design.  The heavy aluminum, die cast and powder coated cases are all-welded construction to prevent deterioration, and available in 8 inch and 12 inch chart sizes. Each unit is handcrafted, made to order in our Asheville, NC USA factory

Available with up to 3 pens, all pressure elements are made of 316SS and are field replaceable.  Choose from our five available case mounting styles: wall, flush, pipestand, portable, or pedestal.

Available Aluminum Case Mounting Styles

Our circular chart recorders are built with weatherproof construction, including a heavy lockable door with weatherstripping, with or without a window.  Designed for outdoor use, the rugged design withstands high levels of vibration and includes one-half inch screened air vent holes in the case, adjustable door pull latch with available locking hasp, all stainless steel corrosion resistant internals, and micro-adjustable wire linkage.

Low pressure elements for ranges 30 PSI and below are 316SS bellows diaphragm, tubing, and fittings.  Standard pressure elements for ranges over 30 to 10,000 PSI are made from 316SS helical coil with stainless steel fittings and tubing, and have 1/4 inch NPT fitting.  High pressure elements for ranges above 10,000 PSI are made from 316SS bourdon tube with autoclave fitting.  High pressure elements are calibrated on the rise only.

Choose from a variety of recorder drives to configure your recorder.  Our most popular option is the PC-11 C-Cell battery powered, eleven speed motor with speeds of 60 minutes, 96 minutes, 12 hours, 24 hours, 48 hours, 7 days, 8 days, 14 days, 16 days, 31 days or 32 days.  Our PC-12 C-Cell battery powered, twelve speed motor offers speeds of 30 minutes, 60 minutes, 2 hours, 4 hours, 6 hours, 8 hours, 12 hours, 24 hours, 3 days, 4 days, and 7 days.  Spring wound drives with standard rotation of 24 hours / 7 days are also available.
