Maximum pressure limiter for liquid gas systems FD16 FEMA / Honeywell

The pressure sensor was designed to be “self-monitoring”, i. e. should the measuring bellows rupture, the pressure sensor switches off towards the safe side. The pressure sensor thus complies with “of special construction” in the sense of VdTÜV Memorandum “Pressure 100”.
FD16 FEMA / Honeywell pressure limiters are used in intrinsically safe control circuits (Ex-protection Ex-i). By using an isolating amplifier, the control circuit is also monitored for line break and short circuit.

Parameter Value
Kind of pressure overpressure, relative
Pressure connection external thread G1/2
Electrical connection terminal connection M16x1,5
Protection class IP65
Housing material rugged housing of seawater resistant aluminium die casting GD Al Si 12
Media temperature -25 ... 60C
Media temperature limit temperatures up to 60 oC are allowable for short periods. Higher temperatures are possible, provided that the limit is safeguarded by suitable measures (e.g. water tube trap, see Accessories for Pressure Switches / Transmitters)
Ambient temperature -25 ... 60°C
Ambient temperature limit at temperatures below 0 oC, ensure that no water condensation can arise in the sensor and in the switching device
Switch function/capacity SPDT Microswitch with resistor combination for circuit- break and short-circuit
Pressure adjustment range 3 ... 16 bar
