The ACSI Glass Level Sensor provides highly accurate glass level measurements from reliable, design- simplified, and cost effective equipment. The sensor measures glass level up to .0004” (0.01 mm) resolution and can be adjusted throughout the range of operation.

Accessible components and basic design simplicity result in easy operation; self-lubricating fittings and durable, high temperature construction reduce maintenance downtime. The ACSI Glass Level Sensor provides uncomplicated reliability, and requires none of the paperwork associated with nuclear measuring devices.

Probe Mechanism

• Micro Adjustmenbt Mechanism - enables adjustment to .0004" (0.01 mm) during operation.
• Clamping Block – utilizes high temperature insulating material designed to secure up to 1-1/2” (38.1 mm) conduit for probe support.
• High Temperature Bellows – high temperature silicon impregnated cloth bellows protects shaft and spring.
• Self-lubricating Fittings – provide low maintenance and less downtime.
  

  Probe Drive Motor

• Honeywell #10260 – standard type motor, should replacement ever be necessary. Other motor types available as option.
• Large Handwheel – enables quick, simple height adjustment.
• Auto/Manual Switch – allows local control of the electrical Raise and Lower functions during installation.
• Glass Contact Light – gives local indication of probe glass contact.

Probe Type

Ceramic protection tube, platinum electrode. Thermocouple-type connection head, threaded to receive 3/4” (19 mm) thick-wall conduit.

Probe Mounting Arm

Standard 3/4” (19 mm) thick-wall electrical conduit. (Not supplied).

Resolution: 0.0004” (0.01mm)

Resolution specifications based on 12-bit A/D conversion. Usable resolution depends on choice of position feedback device (solid-state 4-20 milliamp sensor or wirewound slidewire), stability of mounting, and length of probe mounting arm.

Typical Control: 0.01” (.25 mm)

Control depends on furnace type, location of glass level sensor, stability of furnace pressure, and accuracy of level control tuning +/-0.01” (+/-.25 mm) observed. With higher resolution input capability, +/- 0.002 (+/- 0.05 mm) observed.

Output Signal: Linear with position based on 0-5, 1-5 Volt or 4-20 Milliamps.

The calibrated travel limits are -.5 to +.5; however, the overall mechanical travel limits are -.8 to +.8.

Ambient Temperature: 120° F (50° C) Normal; 160° F (70° C) Peak
