Loggers is uniquely suitable for compactly configuring a data acquisition environment using a PC as a human interface. Model 8040 is available in two versions, a half 19" rack module that can acquire data from upto 48 channels, and an expandable full 19" rack module with a maximum of 112 channels. Both versions internally log and also transfer measured variable in real time to PC. They are remotely controlled by the host computer through a set of commands and transmitted in a RS-485/RS232 network. The modular design also provides more flexibility in the system configuration.

 

The Datalogger system architecture includes a power supply card, CPU card with a built-in RS-232/RS-485 communication port, input and output cards. Datalogger enables user to log the real time data with time stamping. One can select input channel number for log and print purpose with specified time interval from operator terminal keys or using Masibus mACplus software. Print on demand facility is also available. mACplus software works on windows platform and is used for datalogger configuration, calibration and retrieving logged data to PC.

 

Alternatively, operator terminal is used for local display, configuration and programming of datalogger. Operator terminal is equipped with 24 keys and uses 2x16 alphanumeric LCD screen as user display interface. Model 8040 is much smaller and lighter than our previous model occupying significantly less space. It can provide high speed measurement having a scanning speed of 1 second for 112 channels. Provision for 8 channel DO module provides alarm signal to annunciate abnormal process condition. 4 alarm levels per channel can also be configured.

Muffle Furnace

A muffle furnace (sometimes, retort furnace) in historical usage is a furnace in which the subject material is isolated from the fuel and all of the products of combustion including gases and flying ash. After the development of high-temperature electric heating elements and widespread electrification in developed countries, new muffle furnaces quickly moved to electric designs.

Today, a muffle furnace is (usually) a front-loading box-type oven or kiln for high-temperature applications such as fusing glass, creating enamel coatings, ceramics and soldering and brazing articles. They are also used in many research facilities, for example by chemists in order to determine what proportion of a sample is non-combustible and non-volatile (i.e., ash). Some digital controllers allow RS232 interface and permit the operator to program up to 126[citation needed] segments, such as ramping, soaking, sintering, and more. Also, advances in materials for heating elements, such as molybdenum disilicide offered in certain models by Vecstar, can now produce working temperatures up to 1800 degrees Celsius, which facilitate more sophisticated metallurgical applications.[citation needed]

The term muffle furnace may also be used to describe another oven constructed on many of the same principles as the box type kiln mentioned above, but takes the form of a long, wide, and thin hollow tube used in roll to roll manufacturing processes.[citation needed]

Both of the above mentioned furnaces are usually heated to desired temperatures by conduction, convection, or blackbody radiation from electrical resistance heating elements.[citation needed] Therefore there is (usually) no combustion involved in the temperature control of the system, which allows for much greater control of temperature uniformity and assures isolation of the material being heated from the byproducts of fuel combustion.

We are one of the reckoned manufacturers, suppliers and exporters of a wide range of muffle furnaces that is used in various industries. Fabricated as per the set industry standards, these are widely used for heating purposes in chemical and R&D industries. We also offer customize solutions of our Muffle Furnaces at market leading prices.
