Photodetector Modules for Velocity Model PDM 1000-1

 TSI PDM 1000-1 Photodetector Module is used in TSI single-component LDV systems.

Probe - Transceiver Probe 15mm Diameter 1-Component

The 1-Component Transceiver Probe's 15 mm outer diameter, selection of multi-purpose (in-air or submerged) lenses, and fully sealed stainless steel construction make this the most compact and versatile LDV probe available.

Probe - Transceiver Probe 25mm Diameter 1-Component

The TR120 Transceiver Probe provides the ability to make velocity measurements in difficult to access situations. The probe is compact, sealed, rugged, and operates in the backscatter mode, with receiving optics built in.

Probe - Transceiver Probe 83mm Diameter 1-Component

The TR160 Transceiver Probe is our most popular one-component LDV probe. Easy to set up and use, it operates in the backscatter mode, with receiving optics built in.

External Input

TSI External Input Card Model EB  allows input of up to 4 channels of analog data, including the once-per-rev(OPR) signal.

External Input Card Module

The External Input Card module allows input of four analog and one once-per-rev (OPR) signal, plus up to four channels of digital data, all using a convenient interface box with Status Light, BNCs, and D-Sub connectors.

IC Engine Probe Adaptor

These probe adaptors allow time-resolved, spatially resolved, even cycle-resolved, flow measurements in unmodified IC engines. These need no separate optical access and are used with TR 110 or TR 210 fiberoptic probes.

Laser Power Meters

TSI Laser Power Meters provide a convenient and accurate way to measure Ar ion beam powers, to keep your LDV or PDPA system running at peak efficiency.

Laser Safety Glasses

TSI Laser Laser Safety Goggles provide a solid protection from direct and scattered laser beams. We take the guesswork out of selection and purchase of Ar ion, YAG, and YLF safety eyewear, so you can focus on using the system.

Mount Kits for LDV

Mount Kits for LDV provide the rugged but precise mounting base needed to get the maximum performance from LDV systems. Easy adjustment and long-term stability are key features of the TSI Mount Kits.

Oil Droplet Generator

The Oil Droplet Generator (TSI Model 9307) is used to produce large quantities of oil droplets for seeding flows when making PIV or LDV measurements. The large droplet output is especially useful for seeding high-speed flows.

Polarization Axis Finder

The 10901A Polarization Axis Finder is a unique tool that provides instant indication of a laser beam's polarization axis. No twisting or turning is required.

Rails for LDV

TSI Rails provide the most flexible and sturdy support system for any LDV system. Various lengths are available, to customise the system to the probes and focal lengths used.

Seed Particles

TSI offers a full range of seed particles to satisfy even the most difficult measurement requirements. Available in a full range of materials and sizes, TSI seed particles maximize the potential of PIV and LDV systems.

Single-jet Atomizer

TSI's Model 9302 single-jet atomizer generates a polydisperse aerosol stream from a compressed air source. External pressure control and a flexible outlet tube allow the user to put the right amount of aerosol right where its needed.

Six-jet Atomizer

The Six-Jet atomizer from TSI is used to generate a polydisperse aerosol in high concentrations, which can be used as seed particles for PIV and LDV measurements. External controls adjust the number of active jets and dilution air flow rate.
