Digital salt-meter ES-421

The digital salt-meter, ES-421 employs a funnel-shaped sensor section ( conductivity ), which measures the salt % of a sample ( dilute solution of soy sauce, ketchup,mayonnaise, Worcester sauce, sqeezed juice of pickles, etc. ) very small sample needed ( 1.0ml approx. is enough for measurement ). ... more

WA170 MECHANICAL FLOAT SWITCH

Low voltage mechanically-activated float switch for low current panels and alarms

FEATURES:

  • Mechanically activated, snap action contacts
  • High impact, corrosion resistant polypropylene float housing
  • Low current, non-arcing applications
  • UL Listed for use in non-potable water and sewage, CSA Certified, and passed NSF Standard 61 protocol

Mechanical Float Switch Product Description

The WA170 Mechanical Float Switch offers a reliable low current control for AC and DC applications in potable water, wastewater, and sewage.  The internal switching mechanism has sealed gold cross-point contacts for reliable low current operation.  Common applications include: alarm dialers, pump controllers, SCADA systems, intrinsically safe barriers, solar applications, and other low current control and alarm applications.

Models to Meet Your Needs
We offer a Normally Open (NO) model for high level applications.  This model’s control switch turns on (closes) when the float tips 45 degrees above horizontal signaling a high level, and turns off (opens) when the float drops 45 degrees below horizontal.  We also offer a Normally Closed (NC) Model for low level applications.  This model’s control switch turns on (closes) when the float drops 45 degrees below horizontal signaling a low level, and turns off (opens) when the float tips 45 degrees above horizontal.
