Are your chillers driving up your utility bill?

HVAC and refrigeration systems represent between a quarter and a third of total electricity consumption in an average commercial building. Chillers are responsible for over 40% of that demand, making up between 10-12% of a building’s total electricity usage and presenting an opportunity for cost savings. So why are HVAC chillers rarely optimized for efficiency?

5 Considerations When Selecting a Pressure Transducer for Industrial Applications

1. Pressure

The first and most important consideration is pressure. A number of questions must be answered to ensure the correct transducer is selected. What is the pressure range that the transducer will measure? What is the maximum pressure the transducer will encounter? What is the potential for over pressure in the system?

What is the Difference Between Unidirectional and Bidirectional Pressure Transducers?

Unidirectional Pressure Transducers

Unidirectional pressure transducers measure between zero and a positive pressure. The diaphragm of the sensor should only move in one direction and will produce a positive voltage or milliamp output.

How to Troubleshoot a Pressure Transducer

Pressure transducers today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration.

Capacitance & Inductive Pressure Sensors

Capacitive Transducers

Setra’s capacitive pressure transducers are expertly designed adaptations of a simple, durable and fundamentally stable device...the electrical capacitor. In a typical Setra configuration, a compact housing contains two closely spaced, parallel, electrically isolated metallic surfaces, one of which is essentially a diaphragm capable of slight flexing under pressure.

Does Your Product Fall Under New RoHS2 Restrictions?

Newly Added Restricted Products Under RoHS2 Affects Manufacturing

In 2013, RoHS2 was created by the European Union legislation, nearly a decade after the original RoHS (Restriction of Hazardous Substances Directive) was implemented.  RoHS2 is merely an evolution of RoHS1 that provides greater clarity on the legal scope of products that should adhere to the hazardous material guidelines. The combination of
