Yokogawa 261 Taut Band and Iron Vane Window Mount Stylist

Stylist analog panel meters are available in Window mount or Surface mount styles. Optional bezels for Surface mount permit rear panel mounting. Standard movement torque to weight ratio is approximately 4 times greater than most other manufacturer's high torque versions.
 
Note: Severe-duty panel meters are available to meet/CUL or /UL 1437 requirements in 2 1/2"-4 1/2" sizes. To order, add /UL or /CUL after catalog number.

Window Mount Iron Vane, Pivot & Jewel - Model 261

Pivot & Jewel - In this design the coil and pointer are supported by polished steel pivots at each end which fit into jewel bearings. Pivot and jewel meters are recommended for high- vibration environments because of the mechanism’s inherent stability and strength. Accuracy and repeatability are almost equal to the taut-band’s, and good performance from the pivot and jewel construction is the reason for its long popularity. Don’t specify pivot and jewel meters for applications that involve high shock, but do take advantage of this meter’s ability to withstand vibration.

Window Mount Taut Band - Model 261

Taut band is a means of suspending the moving mechanism between two ribbons of metal, obviating the need for pivots, jewels and control springs found in conventional mechanisms. The absence of friction resulting from this permits greater sensitivities and provides more rugged meters.Common failures of conventional meters subjected to shock testing are cracked jewels and/or blunted pivots. Taut band, without pivot and jewels, consequently, will withstand shock in excess of that specified for pivot and jewel meters. For example, ANSI Specifications for panel meters require 50G shock. Taut-band meters will withstand 100G shock.
