The design of a switch mode power transformer will differ depending upon the type of circuit used. There are many variations of switching mode power supplies, but they can be narrowed down to three basic circuit configurations (each also has a mirrored configuration); buck, boost, and fly back. Be aware that the name for the buck circuit varies from industry to industry and from person to person. It may also be referred to as an inverter, d.C. Converter, forward converter, feed forward, and others. There are also unipolar and bipolar (push-pull) versions.

Features :

* non-corrosive
* light weight
* long lasting
* high performance

An additional advance in the case of metal oxide sensor technology is the use of AC rather than DC interrogation of the sensing material.This approach provides complementary atmospheric composition information from the real part and the imaginary part of the sensor impedance and introduces a marked enhancement in terms of sensitivity and selectivity.

The SMS is designed to work with up to 8 metal oxide gas sensors. It has circuits to accurately control sensor heater temperature based on digital control loops. The individual sensor heater 'C resistance and temperature coefficients can be set, and there are a number of heater setpoint algorithms that can be selected as parameters.These include temperature ramps, timed temperature schedules and control by an external RS485 interface.Temperature setpoint algorithms can be set in pairs, or slaved to the first pair as required.

The SMS unit measures the impedance of the sensing element by applying a controllable synthesised sine wave to a potential divider formed by a top resistor (selectable between 100kR and1MR by an on-board jumper) and the sensor:

The sensor resistance is displayed by the PC monitor software, as is a measure of the quadrature (reactive) component.

Specification
4 or 8 MMO sensor channels, configurable for a wide range of MMO sensors.
digital control of heater temperature using an adaptive algorithm and a number of heater temperature profiles to aid selectivity.
measurement of real and imaginary sensing element impedance.
usable with a wide range of sensors, to sense alternative gases.
a range of interface options including CAN, RS485 and RS232.
supplied with a suitable mains to 12V power supply plug.

EKO Heat Flow Sensors MF-180 MF-180M MF-190 MF-200

EKO Heat Flow Sensors are suitable for the direct measurement of heat flow inside materials, and the measurement of the radiant flow emitted by bodies such as refrigerators and containers.

Principle of thr measurement
There are three modes in heat transmission,thermal conduction, radiation and convection. If the heat flow sensor is placed on the surface of the material, it measures the total value of those three modes. If the sensor is placed inside the material, it directly measures the heat transmission caused by thermal conduction.

1.General description
The luminox family (lox) is a range of factory calibrated oxygen sensors which measure ambient oxygen partial pressure (ppo2) levels using the principle of fluorescence quenching by oxygen.
By default luminox measures ppo2 (mbar) and temperature (°c). An optional pressure sensor enables luminox to also measure barometric pressure (mbar) and to convert the ppo2 reading to an oxygen concentration (o2%).
The sensor benefits from low power operation, traditionally associated with electrochemical sensors, while providing a much longer lifetime due to the non-depleting sensing principle.
Luminox is ppo2 and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional system components. Unlike other sensor technologies, luminox is very stable and robust, does not contain lead or any other
Hazardous materials and has negligible cross sensitivity to other gases.

2.Cleaning
The housing of the sensor can be cleaned using a damp cloth. The sensor should not be immersed in any cleaning media.
Full application and technical support can be provided by our knowledgable and highly experienced engineering team if required.

Factory calibrated methane sensor module for methane sensor tgs2611
Model number: ngm2611

Features:
* factory calibrated
* temperature compensation circuit
* low power consumption sensor tgs2611
* compact size
* meets rohs regulations

Applications:
* residential natural gas alarm

Description
The ngm2611 is a pre-calibrated module for natural gas alarms which is precisely
Calibrated in figaro's humidity and temperature controlled facility.
The most important process in manufacturing reliable resdential gas alarms is
Adjusting the alarm point. Calibration is a complicated and time consuming
Process which also requires a substantial investment in calibration equipment. By
Eliminating the costly calibration process, this module enables users to easily and
Simply manufacture residential natural gas alarms. Figaro has taken the complexity
Out of designing a gas detector circuit by providing users with a temperature
Compensation circuit which combines a built-in thermistor and individually adjusted
Load resistor together with figaro’s low power methane gas sensor.
A connector allows easy replacement of the module for the purpose of periodic
Sensor renewal. This input/output connector enables easy installation of the
Module into the gas detectors’ mother board. This same mother board can be
Used for both methane and lpg gas detectors by simply changing the module.
This module is designed to meet the performance requirements of en50194, and ul1484.
Please refer to “technical information for tgs2611” for sensor sensitivity characteristics.
Refer to “application notes for tgs2611” for further information regarding circuit design.
