Model 177A  Four-Channel Fieldmeter and Alarm System
The only intrinsically safe system that continuously monitors the critical points in your facility to detect and warn of electrostatic buildup before it becomes a problem. 

In a typical scenario; as static levels in your application surpass a preset value, beyond which there may be a danger to personnel or possible disruption or destruction of the process or product, an initial warning is triggered and the process is allowed to continue.  If the problem is rectified, the “warning” returns to a “normal” state.  If the condition persists and the static level exceeds a second more critical value, an alarm is activated terminating the process until corrective action is taken and the system is reset.

Accurate, versatile and dependable, unattended operation makes the 177A ideal for applications such as:

*  Converting, coating, and printing processes
*  Dry particle transport systems
*  “Static-free” environments
*  Explosive atmospheres -- safely monitors potentially hazardous sites to detect charge buildup.  Model 1036 Sensors are Factory Mutual Research approved:  Class I, Division 1, Groups C and D hazardous locations.

Features:

*  Intrinsically safe sensor operation (with optional barriers) in explosive atmospheres
*  4 channel Static Monitor detects static levels in as many as four locations up to 1000-ft away
*  Accurate and drift-free measurement including ionized environments
*  Provides analog outputs and control via RS232/485 and front panel
*  Control and data acquisition, configuration via RS232/485 using MODBUS interface format
*  Built in, fully configurable dual level alarms programmable via front panel, PC or PLC
*  Cascade up to 32 units via RS485 providing 128 sensor locations
*  Simple Windows GUI interface for set up and control
*  PLC compatible using MODBUS protocol
*  Password security
*  “Fail safe” relay configuration
*  “Bad input” protection or console failure indication

1036E Probe
The model 1036E is designed for industrial applications where ruggedness is vital.  This unit is housed in heavy-duty Crouse Hinds 1/2-FS1 electrical boxes with stainless steel covers

1036F Probe
The model 1036F is smaller and lighter for applications where ruggedness is not vital.

Both types have built-in provisions for purging with filtered air or inert gas to prevent drift and to provide additional safety in hazardous areas.  (Both Model 1036 sensors are approved by Factory Mutual for use in hazardous locations.)  Gas flow in the smaller 1036F is through the sensitive aperture only.  To ensure thorough purging in the larger Model 1036E, gas flow is directed across the face of the probe as well.
