Analog Optoisolators
PerkinElmer Optoelectronics, a leading manufacturer of analog optical isolators (AOI) for over twenty years, makes a broad range of standard parts under its trademark VACTROL®.
There are many kinds of optical isolators, but the most common is the LED/phototransistor type. Other familiar types use output elements such as light sensitive SCRs, Triacs, FETs and ICs. The major application for these silicon based devices is to provide electrical isolation of digital lines connected between different pieces of equipment. The principle of operation is very simple. When an input current is applied to the LED, the output phototransistor turns on. The only connection between the LED and phototransistor is through light - not electrically, thus the term optical isolator. These optical isolators are primarily digital in nature with fast response times for interfacing with logic gates. Rise and fall times of a few microseconds, faster for some isolators, are typical.

Optical Isolators provide lasers with immunity from back-reflection, thereby improving the signal to noise ratio for laser diode based transmitters. This is especially important for high data rate transceivers and transponders, or those devices requiring long span lengths between transceiver pairs. All of our isolators are based on dichroic polarizing glass and Faraday rotating crystals for highest performance. These devices are available in a single stage, 1.5 stages, or double stages, with multiple stages providing progressively higher isolation.
LightPath offers isolators in various form factors including: Cylindrical, Surface-Mount, and Sub-Mount. In addition, we manufacture isolators with either an epoxy-free optical path or with a laminated core. The primary benefits of our approach to manufacturing include reduced costs as a result of higher yields, throughput and product consistency as a result of automation. LightPath is capable of delivering a total solution to its OEM customers, from prototype and development contracting through high-volume production.

In the process control and automation field, often the need arises of interfacing low level signals generated by thermocouple, Pt-100, load cell, current and voltage transducers, LVDT etc.. to the process controllers, PLC, DCS etc.. Also, one signal needs to be fed to the multiple control device. To take care of common ground loop of many sensors to single system and also avoid loading effect, isolation of these signal from one another is must. The models featured here provides optical and/or galvanic isolation between input and output, maintaining the desired level of accuracy and linearity.
APPLICATIONS
For conversion and isolation of low level dc signals to (4-20)mA signal for interfacing to PLC, SCADA, DCS etc..

DEBEM automatic pulsation diaphragm dampeners are known for their high performance and sturdiness. They are used below stream from diaphragm pumps on the delivery circuit to minimise pressure differential; they are used with fluids that have an apparent viscosity of up to 50.000 cps (at 20°C) even with the presence of suspended solid parts of a considerable size.
DEBEM dampeners adapt automatically to the system's conditions without the need for manual regulation or calibration.
Its high capacity to minimise pulsations, vibration and air hammer make it a piece of equipment that safeguards and evens the fluid pumped.
The vast choice of construction materials allows you to determine the best chemical compatibility with the fluid and/or the environment without forgetting the right temperature field.
The dampeners are also available for use in potentially explosive environments (ATEX certification).

The use of dosing pumps involves pulsations. The rule is: the longer the line, the larger the pressure peaks. These may impair the operation, in some cases even the pump and / or the line network may be destroyed.
The PDS inline pulsation dampeners from Lutz-Jesco is a simple and also effective way to reduce pressure fluctuations to a harmless level. Due to a choice of different materials it is possible to ensure chemical resistance even in the case of very aggressive media. As the unit is integrated directly into the line the diaphragm storage is flushed continuously, and extra costs because of difficult installation work are avoided.
When mounted close to the pump, optimum results can be achieved. The PDS can be installed on the discharge as well as on the suction side. On the suction side, it often makes reliable metering only possible due to the improved flow conditions. Thus cavitation is also avoided, for example.
The PDS is needed whenever pulsating flow is undesirable or rigid piping and long suction and discharge lines are used. Its maximum stroke volume is 1,200 ml/stroke.
