Высокоскоростной беспроводной многоточечный силоизмерительный комплекс FlexiForce WELF 2 High Speed

FlexiForce® Multi-Handle WELF 2 System High-Speed

The Multi-Handle Wireless ELF™ 2 High-Speed System is a user-friendly, cost-effective load measurement system. This system combines:

• 3 FlexiForce® WB201 sensors
• Battery-operated WiFi transmitter (certified 802.11b radio- 802.11b/g/n compatible)
• Windows-compatible software*, turning your PC or laptop into a force measurement instrument. The WELF2 system, sampling rates up to 6000 Hz
• An unsecured router is required for multi-handle use.
• 3 AAA Batteries

*Compatible with Windows 2000, XP, Vista, and Windows 7

Please note: (1) sensor requires (1) transmitter to measure (1) point. If you need to measure additional points, you need to purchase additional transmitters and sensors. Volume discounts are available for more than 5 additional transmitters (handles). Multi-Handle Systems can work with up to 16 transmitters (handles) maximum.

To purchase more than 4 additional transmitters or if you already own a WELF system and wish to purchase additional transmitters, please contact us at info@tekscan.com or call (617) 464-4283.

For more detailed information on the Multi-Handle Wireless ELF System, including how to set it up and take force measurements, please download the ELF User Manual.

Physical Properties of the WB201 Sensor

Thickness:  0.208 mm (0.008 in.)

Length:  228.6 mm (9 in.) End-to-end

Width:  14 mm (0.55 in.)

Active sensing area:  9.53 mm (0.375 in.) diameter

Connector:  Custom interface to ELF Data Acquisition System

Recommended Max Force

(Adjustable gain feature of the WELF2 System allows you to set force ranges)

Typical Performance

Linearity (Error):  < ±3% (Line drawn from 0 to 50% load)

Repeatability:  < ±2.5% of Full Scale (Conditioned Sensor, 80% of Full Force Applied)

Hysteresis:  < 4.5 % of Full Scale (Conditioned Sensor, 80% of Full Force Applied)

Drift:  <5% / logarithmic time (Constant Load of 90% sensor rating)

Response Time:  < 5 µsec (Time required for the sensor to respond to an input force; Impact load ― recorded on Oscilloscope)

Operating Temperature:  -40°C ― 60°C (-40°F ― 140°F)*

* Force reading change per degree of temperature change = ±0.2%/°F (0.36%/°C)

* For loads less than 10 lb, the operating temperature can be increased to 74° C(165° F)
