Configured for Continuous Tone, this audible alarm suits temperature controller alarm signaling and panel-mounted machine alarm indication.
Configured for Continuous Tone, this audible alarm suits temperature controller alarm signaling and panel-mounted machine alarm indication.
OMEGA® Series 70A temperature alarms are the latest development in solid state sound production. When power is applied, a piezoelectric transducer operates as a solid state oscillator resulting in a loud, audible alarm tone.
