Safety information 

1.1.  Dangers of maloperation 

The 

WSPS 05

 underwent a safety and acceptance test based on IEC 1010-1/EN 61010 

– 1 

part 1. Integrated electronic and hydraulic elements serve protection purposes and ensure 
safe handling if used the conventional way. False operation or abuse, as well as 
insensitivity for the device’s limits and safety instructions will result in immediate danger for 
the following:  

 

 

the operator’s health and life, 

 

the 

WSPS 05

 and all systems it is connected to, 

 

the accuracy of the 

WSPS 05

 

the environment. 

 

This manual includes information and safety instructions, which guarantee safe handling 
and support your devices unobjectionable condition. 

Therefore it is a necessity for all people who operate, install or maintain this device to mind 
this manual. 
 
 

1.2.  Conventional use 

With this 

WSPS 05

 you have purchased an effective diagnostic system for the saturation 

level of water in oil. It operates very reliable and meets the requirements of daily use.  

The set is recommended and tested for the use with:   
 

Standard hydraulic oils: 

HL, HLP 

Triglyceride: 

HETG 

Aircraft hydraulics:  

Mil H 5606 

Synthetic ester: 

HEES 

Lubrication oils: 

CLP 

 

 
 
 

Limits: 
 

Maximum acceptable pressure at the sensor 

25 bar  

(362,5 psi) 

Maximum oil temperature 

90° C  

(194° F) 

Maximum acceptable flow rate at the sensor 

2 m/s  

(6,5 ft/s) 

 
The 

WSPS 05 

should always be operated with 12...30 V DC!
