Fig. 1: Temperature sensor in a pocket, for installation from side. Typically used in stand-alone temperature monitoring system configuration. Sensor elements used are Pt1000 or Pt100.Another application of this sensor is for temperature monitoring in cargo tanks, when radar is used for ullage monitoring.Accuracy of temperature measurement is <0,5C
Fig. 2: Combined water ingress detection and temperature sensor. Only used as a part of our Water Ingress Detection System. This sensor has no application as a stand-alone temperature monitoring system configuration. Mesuring temperature is a secondary means of water detection in some dry bulk cargoes like grain, coal or chemicals, which exposed to excessive humidity tend to increase temeparture as a result of germinations or chemical reactions.Accuracy of temperature measurement is <0,5C
Fig. 3: Combined pressure and temperature sensor. Typically used in heated cargo tanks or HFO tanks with temperature of max 130C. sensor is in Inconel and offers extreme resistance to corrosion.This sensor is ueed for simultaneous measurement of weight/level of the liquid in tank and for temperature monitoring, which is also used for compensation of the readings of the hydrostatic pressure. Accuracy of temperature measurement is <0,5C
