BDT

Features

The Bimetal thermometer employs a bimetal strip in the form of helix (it works on the principle of thermal expansion - two metals having different coefficient of expansions are joined to form a bimetal. The resultant expansion of bimetal is proportional to temperature). Bimetal dial thermometers are simple in construction, yet rugged. They are used for measurement of temperature in most of the industrial o applications. They are offered in the range of (-)50 C to 600 C. With rigid stem having bottom or back entry. It can also be offered in every angle rotatable construction. 
 

Rugged construction

Bottom / Back entry, every angle construction

Fast response

Protection class IP-67

Accuracy ± 1% FSD

High repeatability, low hysteresis

Hermetically sealed case

LDT-R / LDT-C

Features

Liquid filled system based on liquid (other than mercury) expansion principle is used for measuring temperature 0 ranging from (-)30 C to 250 C. 

It has faster response and the same is available in rigid stem as well as capillary type for remote sensing. Every angle type can be offered in all SS construction. Generally used where mercury type thermometer is not used in industries such as Food, Pharmaceutical, etc. The main advantage is its minimum immersion length required for sensing (as low as 30mm suffices for proper sensing thereby making it ideal for installing in lower line sizes).

Rugged construction

Rigid stem or capillary type

Suitable for pharmaceutical, food, biotechnology industry

Protection class IP-67

Accuracy ± 1% FSD

Minimum immersion length (as low as 30 mm suitable for lower line sizes possible)

Case compensated system

GDT-R / GDT-C

Features

Gas filled Temperature Gauge overcomes most of the limitations of other members of 0 family. It is offered in a very wide temperature range i.e. (-)200 to 800 C. Practically any stem length can be offered and capillary length as long as 25 mtr, without any loss of accuracy. Inert, non hazardous, non toxic nature of the filled system makes it virtually ideal choice of cross section of industries.
