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

HIGH LEVEL AND OVERFILL ALARM SYSTEM

COMPONENTS TECHNICAL CHARACTERISTICS AND DIMENSIONS

Depth is 175 mm

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

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 isolator 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

MAGNETIC LEVEL MEASURAMENTS ITMLM

PRINCIPLE OF OPERATION

Resistors network and reed switches are incorporated in

the stem. The float with built-in magnet moves with liquid

level and activates reed switches. Resistor network

changes value due to operation of reed switches. Over

signal converter, resistance is converted to analogue signal

of 4-20mA. Signal converter is inside of the connection

head but can be also delivered in separate box.
