Handwheel Position Indicators Analog Digital Display Systems

The two main types are gravity reaction indicators and fixed reaction indicators. Gravity reaction indicators work on horizontal or slightly inclined shafts, while fixed reaction indicators work in any position including vertical shafts. Additionally, displays come in analog dial only, analog-digital combination with 4-digit or 5-digit counters, and dual pointer systems.

These indicators feature IP64-IP65 protection ratings and are resistant to solvents, oils, and grease for industrial durability. They are constructed with chemical-proof materials and can operate at temperatures up to 80°C, making them suitable for harsh manufacturing and chemical processing environments.

Analog-only displays provide visual position feedback through dial pointers, suitable for applications requiring quick visual reference. Combination analog-digital displays add 4-digit or 5-digit counters for precise numerical position tracking, ideal when exact positioning values are critical for process control or documentation requirements.

Custom machining services are available including bored holes, splines, keyways, and transversal bores upon request. Indicators are compatible with handwheel sizes ranging from 60mm to 200mm diameter and offer multiple mounting and configuration options. Both steel and aluminum hub materials are available depending on application requirements.

Yes, fixed reaction indicators are specifically designed to work in any position including vertical shafts. Gravity reaction indicators are limited to horizontal or slightly inclined shafts. When selecting an indicator, the shaft orientation determines whether you need a gravity reaction or fixed reaction type system.

Reduction ratios range from 2:1 up to 400:1 depending on the specific model. Lower ratios (2:1 to 36:1) provide faster dial response for applications requiring quick visual feedback, while higher ratios (up to 400:1) offer extremely precise control and finer position resolution for critical positioning requirements in valve control and process equipment.

Yes, these indicators are specifically designed for chemical processing applications with chemical-resistant construction that withstands exposure to solvents, oils, and aggressive environments. The IP64-IP65 protection ratings and chemical-proof materials ensure reliable operation in demanding industrial settings. Optional glycerin filling is also available for additional vibration damping.
