Краткое введение о BHB, BAM, и BAB250℃

Specifications

1) BHB Series
Полностью влагозащищенный тензорезистор с фольгой решеткой из константана и подложкой из эпоксидной смолы, армированной стекловолокном. Одновременно с функциями термокомпенсациии и с компенсации ползучести.
Характеристики:
превосходная стабильность в широком температурном диапазоне, влагостойкость, низкая гигроскопичность, хорошие свойства по компенсации ползучести и возврату ноля. Прежде всего, предназначены для высокоточных преобразователей классе точности С3 и выше.

Key Specifications:

2) BAM Series
Special polyimide film backing, the BAM series offer better creep and back to zero function. With thin backing film, good heat resistance (stability is lower than 35PPM), low hydroscopicity(lower than 0.6%), excellent performance and easy bonding, BAM series are suitable for Class C3 and higher accuracy load cells manufacturing.

Strain Limit(%) 2.0 Fatigue Life 10000000
Insulation Resistance(MΩ) 10000    

3) BAB 250℃ Series
Imported Glass Fiber Reinforced Polyimide backing, BAB series offer excellent heat resistance, good insulation, thin
backing film, high stability and are suitable for both high precision stress analysis and accuracy transducers with
temperature up to 250℃.

Key Specifications:

Temp. Range(℃) -269~+250 STC Code 9,11,16,23,27
STC Precision(um/m/℃) 1.0 Insulation Resistance(MΩ) 10000
Strain Limit 1.5% Fatigue Life(±1000) 10000000

2. Notes:
1) For BHB and BAM series strain gages, ZEMIC offers the High Performance Epoxy: H-600, H-610. They are accordance
with the function of the strain gages and can be applied as adhesive.
2) The recommended soldering temperature is 280℃, the maximum is 330℃. When soldering, it is better to control the
temperature as well as the soldering time since extra heat is harm for the strain gages, especially the insulation.
3) Be careful and cautious when using BHB, BAB series strain gages, in consideration of the fragility of the backing film.
4) The special requirements of the lead wires should be specified in the strain gages designation system.
