Pressure switch

DSB 1

Pressure sensors

Description
Technical data
Product series DSB consists of mechanical-piston pressure switches
designed for use with NLGI Grade 1-2 greases The location of the Function principle mechanical piston pressure switch
actuating piston inside the pressure switch housing helps to ensure Operating temperature –25 to +80 °C,
–13 to +132 °F
a continuous exchange of grease around the measuring point This Operating pressure max 300 bar, 4 350 psi
reliably prevents the same grease from being pressurized repeatedly, Lubricant oil and grease NLGI 1 and 2
Breaking capacity, ohm load max 1,2 VA
which could cause lubricant soap and oil separation, also known as Supply voltage max 30 V AC/36 V DC
grease bleeding Based on the application, the pressure switch can Supply current min 1 mA, max 50 mA
be configured as a single or double design and with or without a Type of contact change-over
measurement connector or pressure gauge The pressure switch Connection method clamps
generally is installed upstream of the last lubricant distributor Mechanical service life 10 5 switching cycles
Housing material aluminium, anodized
Contact material silver alloy, hard gold plating
Connector socket 3+PE DIN EN 175 301-803 A
