Intrinsically Safe & Hazardous Environment



At Pioneer Scale we understand the important role that Intrinsically Safe equipment plays in the production of volatile chemical compounds.  With over 40 years in the legal metrology industry, Pioneer Scale has a wealth of knowledge to help you navigate the purchase, installation, calibration, and maintenance of your weighing equipment.  Our technicians, sales staff, and management have more than two centuries of combined experience in the scale business.

 

Intrinsically safe environments must be protected from any electrical transient or heat source that could potentially result in an ignition.  This can be achieved in different ways.  One of the simplest is to eliminate the use of AC voltage entirely and operate the scale via an intrinsically safe digital weight indicator with an IS rechargeable battery pack.  In the case of equipment that is utilized in multiple locations or must be moved for housekeeping purposes this may be the only way to achieve the desired protection.

A second method of protection would use and intrinsically safe indicator with an intrinsically safe AC power supply.  This allows the weight indicator to still be at the scale and visible to the operator while still providing the necessary safeguards.

 

A third means of achieving intrinsically safe weighing equipment is via the use of Zener barrier systems.  Zener barriers use special diodes and fuses in conjunction with proper grounding to prevent a dangerous transient from moving from a standard digital weight indicator in a non-hazardous area into the hazardous environment.  It also prevents the voltage at the scale from falling to a point where the internal circuitry might begin to heat up and provide another potential source of autoignition.
