Warning! Do not replace bolts! The bolts are made specifically for this sensor. Replacement of 
bolts made from other materials and /or other specifications may lead to water ingress and 

erroneous measurements. Replacement bolts can be obtained from FTN. 

 

Note:

 If any leakage is found, 

contact FTN for service

. Unrepaired leakages will result in loss of oil and 

possibly loss of function of the sensor. 

Note: 

Do not attempt to refill hydraulic oil without proper tools. Filling tool MK2 TSAS, Part No.: 212124 

shall be used for filling and re-filling of hydraulic oil. Follow the user-manual for the filling tool. Follow the 
safety data sheet on the oil for protective measures. 

Note: 

Do not attempt to replace O-rings other than on the connectors. After replacement of O-rings on the 

pressure bearing components, the sensor shall be pressure tested in 3.5wt% salt water for 30min at 300bar 

following a complete function test in a test test-rig. These tests must be done at FTN. 

 
 

Integration into systems 

 

For mounting 

and use of the sensor on ROV’s and AUV’s, please refer to the FiGS Generic Method Statement 

provided by FTN
