Model 624 – Multiple Channel Static Monitor System


The Model 624 Static Monitoring System is a multi-channel alarm system that continuously monitors the static level and initiates lower and upper alarms when the preset thresholds are exceeded. The system is capable of simultaneously monitoring from one to four channels. The Model 624 features autoranging ±500V to ±5kV or ±5kV to ±50kV ranges, dual alarm thresholds and 4-20mA or ±1 Volt signal outputs. The Model 624 is housed in a water resistant ABS enclosure and utilizes isolated non-contacting vibrating read sensors housed in a cast aluminum enclosures.

AIR PURGE – All static level monitoring sensors include an “Air Purge” fitting which allows the end user to hook up house-air or inert gas to provide positive airflow to the sensor. This prevents hazardous fumes or gasses from leaking into the sensor and its electronics.

INTRINSICALLY SAFE – Intrinsically sensor sensor connections are provided by the customer (The 5-wire sensor would require 5 barriers). ETS does not supply intrinsic barriers. Recommended barriers are covered in the user manual.
