PS-3212 wireless current sensor
The PS-3212 wireless current sensor has a broad current-measurement range for introductory and advanced investigations of electricity and basic circuits. Designed with user safety in mind, it measures currents up to 1 A and has built-in overload protection. Acquired data are transmitted wirelessly to computers, Chromebooks (Google notebook computers), tablets, and smartphones. With a wireless voltage sensor, students can investigate Ohm's law, series and parallel circuits, and more. Because current exists only in a closed circuit, the wireless current sensor must form part of a closed circuit to measure current. It must be connected in series and has very low internal resistance, only 0.1Ω. It is therefore not recommended to connect it directly across a battery or another voltage source without a resistive load. In chemistry, the wireless current sensor helps students count the electrons driving chemical reactions, much as a balance measures the mass of substances in a reaction. Current intensity in amperes determines the number of atoms participating in a chemical reaction; this relationship allows current to be used to calculate the amount of reactant available in a solution. Integrating current also tracks the amount of metal that may be electroplated onto an electrode.

PS-2011 dual-channel Bluetooth interface Sensors Brolight
Interface Type: USB or Bluetooth 2.0 Interface: 4 (2 PASPORT interfaces, 1 voltage interface, 1 temperature interface)
The PS-2011 SPARKlink dual-channel Bluetooth interface lets teachers and students connect their devices by USB or Bluetooth to any of more than 70 PASPORT sensors in the PASCO range. Data are acquired with SPARKvue or PASCO Capstone. Teachers and students can use desktop or laptop computers running either program, or Bluetooth-enabled iOS or Android devices running the SPARKvue app. Note: SPARKlink Air connects to Google Chromebooks by USB but does not support Bluetooth connection to them.

Fully integrated 4-channel DVS optical module Sensors Oe-photonics
Sensing distance: typical:20 km Number of detection channels: 4 channels Modulation mode: External modulation
For multichannel, fully integrated distributed vibration sensing (DVS), the DVS-AOM-L series uses an ultra-narrow-linewidth laser with optimized optomechanical/electrical integration. Serial-port parameter configuration, high integration, environmental-interference resistance, compact size, and convenience are provided. Sharing a narrow-linewidth laser reduces multichannel costs, particularly for demanding sensing applications. Custom solutions and specifications are available to sensor-equipment manufacturers.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
