Teledyne AP00465 Model PX2 LED UV Fluorescence Transmitter with PMT Detector

Overview

The Teledyne AP00465 is the Model PX2 LED UV Fluorescence Transmitter, a photometric detection module built around a photomultiplier tube (PMT) sensor that forms the analytical core of Teledyne API’s UV fluorescence sulfur dioxide and trace-gas analyzer platforms. The PX2 transmitter converts ultraviolet fluorescence emitted by excited SO2 molecules into a precise electrical signal, using a stabilized LED excitation source in place of older, less stable UV lamp designs, resulting in longer service intervals and more consistent baseline performance over the analyzer’s operating life.

With engineering support in Muscat, Seven Star LLC supplies the Teledyne AP00465 PX2 transmitter to continuous emissions monitoring system (CEMS) integrators, environmental compliance laboratories, and ambient air quality network operators throughout Muscat, Sohar, and Salalah. Every unit is sourced through Teledyne’s traceable spares and OEM channel, ensuring full compatibility with existing Teledyne API SO2 and trace-level gas analyzer housings.

Operating Principle

The PX2 transmitter operates on the principle of UV fluorescence: sample gas is exposed to ultraviolet light at a wavelength that excites SO2 molecules to a higher energy state, and as the molecules relax back to their ground state they emit fluorescent light at a longer wavelength, proportional in intensity to the SO2 concentration in the sample. The photomultiplier tube detector inside the Teledyne AP00465 housing captures this weak fluorescent signal and amplifies it by many orders of magnitude, allowing the analyzer to resolve SO2 concentrations down to parts-per-billion levels.

Because the PX2 uses a solid-state LED excitation source rather than a mercury vapor UV lamp, the transmitter reaches optical stability far faster after power-up and exhibits significantly less long-term intensity drift, which translates directly into fewer baseline recalibrations and more reliable unattended operation at remote or difficult-to-access monitoring sites. No moving parts sit in the optical path, eliminating a common source of mechanical wear and contamination found in older photometric designs, and the sealed PMT and LED assembly resists the ingress of dust and moisture common in outdoor CEMS shelters.

Engineering Design of the Teledyne AP00465

The Teledyne AP00465 is housed in a rugged, black anodized aluminum enclosure that shields the sensitive PMT and LED optics from stray light and electromagnetic interference, with a labeled USB interface connector provided for direct digital communication with the host analyzer’s data acquisition electronics. The compact, self-contained module bolts directly into the analyzer’s optical bench assembly using factory-aligned mounting features, preserving the precise optical geometry required for accurate fluorescence detection.

Field replacement follows Teledyne’s documented module-exchange procedure: the analyzer is powered down, the optical bench cover is removed, and the PX2 transmitter is unbolted and replaced as a complete sealed unit, avoiding the need to open or realign individual optical components in the field. After installation, a standard span and zero verification with certified SO2 calibration gas confirms that the replacement transmitter is performing to the analyzer’s original factory specification.

Key Features

The Teledyne AP00465 PX2 transmitter is engineered to deliver dependable, low-maintenance photometric performance for demanding compliance and research applications:
