PS-3225 wireless smart photogate sensor
The PS-3225 is a wireless multifunction smart photogate sensor. Two photogate beams spaced 1.5 centimeters apart measure speed and velocity accurately. Its built-in laser switch, used with any laser device, times objects too large to pass through the photogate-bracket opening. A slot in the bracket accommodates photogate tape, which also helps measure the motion of larger, high-speed objects such as model rockets. An auxiliary port connects an additional photogate head or time-of-flight accessory. Note: Synchronization accuracy is limited to 2 milliseconds, so using two wireless smart photogates in the same experiment is not recommended unless the measured time is relatively long, exceeding 0.5 seconds.

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.

Gas mass flow controllers-3660 series
Sensors
Csl-vacuum
Flow-rate range [Different flow units at the two ends retained as in the source, without conversion]: 10SCCM~100SLM Gas/fluid: N2, AIR, H2, HE, AR, O2, CO2, etc. Electrical connection: Dsub 9-pin
An internal sensor measures gas flow in real time and compares it with the setpoint. The controller rapidly actuates a regulating valve, forming a closed loop that stabilizes actual flow precisely at the target.

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.
