Differential Pressure Switches For Extreme Environments

Dietz Models 170D and 171D low differential pressure switches are now manufactured exclusively by World Magnetics following its purchase of the Henry G. Dietz company, World Magnetics announced. The heavy-duty switches are targeted for use in construction equipment, marine and rail transportation applications, mining equipment and a wide range of industrial applications.

Dietz switches are designed to combine low pressure actuation and rugged construction to deliver precise and repeatable performance in harsh environments. The Dietz Model 171D is vibration resistant, and conforms to MIL-STD-167-1 and MIL-STD-901-D, the company said.

A number of models with factory set actuation points ranging from 0.05 in. H2O (Model 171D) to 40 in. H2O are available. In addition, World Magnetics manufactures a variety of Dietz pressure switches with actuation points that range from 0.7 to 415.6 in. H2O. All incorporate heavy-duty steel, brass, or aluminum housings and mountings designed to provide reliable performance in extreme environments. The product line also includes Dietz airflow switches designed to guard against equipment damage from blower failure or air passage obstruction.
