HNL Pressure Switches

The Series 300 switch range is available for the measurement of pressure (P & PZ) and differential pressure (DP & DPZ). There are pressure ranges for the measurement of gauge pressure above atmospheric pressure (P) and below atmospheric pressure (PZ).

For each of these both electrical and Pneumatic outputs are available. The electrical outputs are available for switches to be used in Hazardous (potentially explosive atmosphere) areas (EExd, EExnC, Exia or I.S. compatible) or for Standard (non-hazardous) areas.

Due to the wide range of options available, a Series 300 switch can be supplied for most applications. In addition to the standard options detailed here HNL can design a switch to your own specification if required.

HNL 700 Series Pressure & Diferential Pressure Switches

The Series 700 switch range is available for the measurement of pressure / differential pressure (P & DP) and temperature (T).

For each of these both electrical and Pneumatic outputs are available. The electrical outputs are available for switches to be used in Hazardous areas (EExd, EExN or Intrinisically Safe) or for Standard (non-hazardous) areas.

Due to the wide range of options available, a Series 700 switch can be supplied for most applications. In addition to the standard options detailed here HNL can design a switch to your own specification if required.
