VLS Series Optical Speed Sensors

The VLS series of Optical Sensors are primarily designed for speed related use, designed originally for use with our range of Digital Tachometers, including hand held, panel mounted and bench style instruments, custom designed variants are available for OEM and volume requirements. They are available with either Visible Light or a Red Spot Laser to suit a wide variety of speed measurement applications and a range of mounting devices is available for hands free applications. General Applications - Ideal for most rotating machinery test applications, datalogging and general speed measurement requirements, the VLS series is ideal where quick , simple installation is required to obtain precise speed measurements quickly with minimal installation work required. VLS Sensors interface easily with almost any type of Digital speed monitoring instrumentation, including the Compact range of Panel and Bench Tachometers (see appropriate webpage). Condition Monitoring Sensors - Standard & custom VLS types available Operational Features and Options • Simple to apply - Very easy set-up - simple operation - low maintenance • Choice of Light source - Visible light or Laser light types available • Long Optical range - 1 metre for Visible light types & 2 metres for Laser versions. • Choice of Power supply - 5vdc or 8-24vdc powered versions available. • Cables Options - Captive cable, standard or custom made with clients connectors • Choice of Connectors - Standard or customised options available for OEM & quantity • Output signal options - Standard NPN, other options available on application • High speed applications - Choose Laser models Mains/battery pack & signal interface - SIPP/1 This mains adaptor/battery pack is available for use with all 5vdc VLS versions, it provides continuous power and a BNC pulse output for condition monitoring and field applications where a local mains supply is not available. Contact measurement - All versions can be used with our Contact Adaptor range
