HIGH LEVEL AND OVERFILL ALARM SYSTEM |
|
|
|
|
|
High level and overfill alarm system consists of our standard products:
| - |
magnetic level switches type ITHLA-1 (single point alarm) and/or ITHLA-2 (double point alarm) |
| - |
electronic cabinet with alarm units type ITDAC-14B and intrinsic safety isolators |
| - |
output light and signalling devices |
| - |
completly separate high and overfill in the same cabinet |
Magnetic level switches connection cables are fully controlled (short circuit, line break, resistance).
System is designed for use on board all types of liquid cargo ships. It is tailor made, following specific requirements and meets requirements of all major classification societies.

COMPONENTS TEHNICAL CHARACTERISTICS AND DIMENSIONS |
|
 |
|
| ITDAC 14B ALARM UNIT |
|
| - |
Microprocessor controlled |
| - |
Can control up to eight alarm points |
| - |
For more than eight points, more units can be used, with common external control buttons and power failure battery |
| - |
Due to analogue inputs, ITHLA-x line condition can be fully controlled |
| - |
Type approved by LLoyd's, BV, DNV, RINA, GL and Croatian register of shipping | | |
|
| MAGNETIC LEVEL SWITCHES |
|
|
Dimensions A,Z1,Z2 and B depends on tank height
|
|
| TEHNICAL CHARACTERISTICS |
|
| - |
Type ITHLA-2 (double point) |
| - |
Type ITHLA-1 (single point) |
| - |
Specially designed for mounting on open deck, robust construction |
| - |
AISI 316L stainless steel construction with flange DN100, NP16 |
| - |
Can be tested from outside of tank |
| - |
A float with built-in magnet is moved with liquid level and activates reed switch fitted inside the stem |
| - |
When high level or overfill alarm is required, single point magnetic level switch ITHLA-1 is used. When both (high level and overfill) alarms are required, double point magnetic level switch ITHLA-2 should be used. |
| - |
Can be installed in dangerous area and connected via intrinsically safe insulator situated in non-hazardous area. (According to explosion protection standards, the equipment is regarded as a "simple apparatus" due to the fact that it contains only passive elements such as reed switch and resistors.) |
| - |
Operating temperature: -25°C up to +90°C |
| - |
Working pressure: up to 4bar for wetting part |
| - |
Connection head protection: IP56 | | |
