Variable force spring and variable torque spring are very similar with constant force spring and constant torque spring. But we diversify the radian by winding the steel strip into a coil. Therefore, it can unfold negative gradient, positive gradient compounded in a spring. Here are some relations between load (force or torque) and stroke that can be used on specific occasion.

Pen Type Drug Injector Application

The spring exerts constant force to keep the drug flow fixed, preventing the patient from feeling uncomfortable when applying it. It features stretch force in end...

The new WebDAQ 904 is a stand-alone universal input data logger designed for remote monitoring and control. All the intelligence is built into the WebDAQ, eliminating the need for a PC or additional software. WebDAQ 904 features four 24-bit simultaneously sampled analog input channels, individually configurable for voltage (up to ±60V), current, RTD, thermocouples, resistance, and bridge-based sensors. 

Data can be recorded to the 3GB of internal storage, to external USB media or SD cards for virtually unlimited storage. By using the embedded WebDAQ web server, users can...

The miniaturized sensing heads are especially developed for the use in small and cramped surroundings and are perfect for applications with limited space, such as midgets instruments and engine constructions. The very advantageous cost-performance-ratio supports the integration of the pyrometers within OEM solutions and simultaneous use of the measurement devices at multiple infrared measuring facilities.

The compact series devices offer inimitable advantages for the installation in applications with high surrounding temperatures, such as within the plastic or paper industry. The...

The Micro-Epsilon eddyNCDT 3060 inductive measurement system is based on eddy currents and enables fast, precise displacement measurements in industrial environments. Based on ease of use and smart signal processing, this non-contact system defines a new performance class in inductive displacement measurement. More than 400 sensor models can be combined with the eddyNCDT 3060.

In contrast to conventional inductive sensors, displacement sensors based on eddy currents stand out due to their high accuracy, bandwidth and temperature stability. Furthermore, this measuring...

A polarisation sensor makes details visible that remain hidden to other image sensors. IDS now offers the IMX250MZR 5 MP sensor from SONY with integrated on-pixel polarisers in the uEye CP camera family. The models ensure better object detection in cases of low contrast or light reflections. They also provide a convenient way of detecting fine scratches on surfaces or the stress distribution within transparent objects.

Both USB3 Vision and GigE Vision are available as interfaces. Using polarisation filters, the sensor generates an image with four polarisation directions...

Measurement Computing adds a new member to its series of DAQ HATs - professional DAQ modules designed for the Raspberry Pi® platform. MCC 172 is a dual-channel module for acquiring IEPE sensor data.

MCC 172 accepts direct connection of piezoelectric sound & vibration sensors according to the popular IEPE standard. Data can be sampled simultaneously with 24-bit resolution and sampling rates up to 51.2 kS/s per channel. No additional signal conditioning will be required for acquiring aliasing-free signals up to 23 kHz. For higher channel count multiple DAQ HATs...

Sensata Technologies announced the availability of the new Low Noise (LN) series of panel mounted solid state relays designed for use in a wide range of consumer and industrial systems and products where precise power control, long life, reliability and reduced levels of electromagnetic noise are required.

Instead of using moving components as mechanical power relays do, solid state relays rely on silicon-controlled rectifier technology which allows SSRs to provide quieter operation (no clicking), longer life, as well as more precise switching control.

The...
