About Emmisivity Measurement Apparatus

Emmisivity Measurement Apparatus:

Micro Teknik

Description:

The present Set-up is designed to measure the emissivity of test plate. The test plate comprises of a mica heater sandwiched between two circular plates.
Black plate is identical with test plate, but its surface is blackened.
As all the physical properties, dimension and temperature are equal heat losses from both plates will be same except radiation loss.
Hence the input difference will be due to difference in emissivity.
Both plates are supported on individual brackets in a enclosure with one side glass to ensure steady atmospheric conditions.
Temperature Sensors are provided to measure the temperature of each plate and surrounding.
Electric Supply is given to heaters through separate variacs so that temperatures of both can be kept equal and is me asured with Digital Voltmeter and Digital Ammeter.

Technical Specifications:

Test plate Diameter: 160 mm (approx.)
Black Plate Dia: 160 mm (Approx.)
Heater (2Nos.): Nichrome Wire Heater. (One each for test plate & black plate)
Digital Voltmeter: 0-300 Volt
Digital Ammeter: 0-2 Amps
DPDT Selector switches: For Digital Voltmeter & Digital Ammeter
Variacs; 0- 230 V, 2 Amp, (2 Nos.)(One each for test plate and black plate)
Digital Temp. Indicator: 0-3000C, with multi-channel Switch

Precise Emissivity Measurement

This equipment offers accurate assessment of emissivity for various materials through a digital temperature measurement system, enabling reliable heat transfer studies. The equipment is suitable for educational use, supporting investigations in thermal physics and engineering. Its single-sample capacity and removable specimen holder simplify experiment setup and versatility, making it ideal for lab demonstrations and training sessions.

Robust Build and User-Friendly Design

Crafted from stainless steel and powder-coated mild steel, the device ensures longevity and ease of maintenance. Glass wool insulation minimizes heat loss, and natural air cooling keeps operations environmentally safe. Bench-top mounting, compact construction, and low-maintenance requirements make it accessible for students and lab personnel alike.

Safety Features and Compliance

The apparatus integrates over-temperature protection and is compliant with IS standards, guaranteeing safe operation during lab experiments. All included accessories, such as measuring cables and the instruction manual, support effortless setup and usage, catering perfectly to academic institutions across India.

FAQs of Emmisivity Measurement Apparatus:

Q: How is emissivity measured using this apparatus?

A: Emissivity is determined by heating the sample with the electrical resistance heater, then recording the temperature using the digital indicator and thermocouple. The instrument calculates emissivity based on the samples thermal response, providing digital readings within the range of 0.1 to 1.0 with a resolution of 0.001.

Q: What is the sample preparation and setup process for testing?

A: To test, prepare a specimen approximately 100 mm x 100 mm, place it in the removable stainless steel holder, and ensure all measuring cables are securely connected. Once the apparatus is powered on, follow instructions from the included manual to begin measurement.

Q: When should the over-temperature protection feature be checked or used?

A: The over-temperature protection activates automatically if the sample or apparatus temperature exceeds safe limits during operation. Regularly verifying its function before experiments ensures both operator safety and equipment longevity.

Q: Where can this apparatus be utilized effectively?

A: This apparatus is best suited for educational institutions heat transfer labs, technical universities, and research organizations requiring accurate emissivity measurements for teaching or experimental purposes.

Q: What benefits does this equipment offer for heat transfer education?

A: By providing fast (<10 seconds response) and accurate emissivity data, the apparatus enhances practical learning in thermal physics, reinforcing theoretical knowledge with credible experimental results. Its semi-automatic manual controls foster understanding of procedural operations, critical for laboratory education.

Q: How do you maintain the apparatus for long-term use?

A: Routine cleaning, periodic checking of electrical connections, and inspection of insulation materials help sustain optimal performance. The robust stainless steel and powder-coated parts require little maintenance beyond standard lab practice.
