BOLA Double Temperature Probes PT 100 Lemo® Compact EX
COMPONENTS FOR EX-PROTECTION
Material: Temperature resistance: Temperature range Chemical resistance: Conductivity:
PTFE-EX from -200°C to +250°C from -50°C to +250°C ++ very good 106 Ohm
Product description:
Two independent sensors PT 100 in a stainless steel tube (1.4571) encapsulated with static dissipative PTFE-EX. Collar ring Ø 12mm, bore dia. 5 mm for earthing connection. The electric circuits are locally separated complying with European Standard EN 61010-2-010:2013. Connection by two couplings (type Lemo®, socket size 1, 4-wire-system) fixed directly at the end of the probe.
Typical response times:
» T 50: 20 - 24 s
» T 90: 30 s
See page 352 for detailed explanation.
Applications:
» avoiding of electric charging
» parallel temperature measurement in aggressive liquids
» double safety due to redundant systems
» control function due to two independent sensors
» Suitable for simultaneous temperature measurement and safety circuit as per the
specifications of the standard DIN EN 61010-2-010 but only one NS/GL socket will be occupied,
separately switched sensors.
» ideal for built-in measurement cables
