0 to 6.8 bar (0 to 100 psia) pressure range with armor

Applications

Continuous static and dynamic pressure measurement in reciprocating-compressor cylinders.
Condition monitoring with the 3500/77M Cylinder Pressure Monitor and System 1 software.
Harsh chemical service when wetted materials and O-ring selection are compatible.
Overpressure-capable measurement within the official proof and burst-pressure limits.

Installation

Mounting torque
Apply 68 N-m (50 lbf-ft) mounting torque.
Diaphragm protection
Prevent tools or foreign objects from contacting the sensing diaphragm.
Electronics support
Secure the electronics housing on or near the compressor using the specified mounting hardware.
Isolation valve
Use a compatible isolation valve and adapter where the pressure-indicator port requires it.

Compatibility

166393-01 3/4-14 NPT or 166393-02 1/2-14 NPT where applicable
Seal compatibility
Select Hifluor or ethylene-propylene O-ring material for the process medium
Model identity
165855-11 identifies the 0 to 100 psia armored range; confirm any separate approval suffix at order stage

FAQ

Q1. How can I verify that the quoted product is the exact 165855-11 configuration?
Require a clear nameplate and package photo showing 165855-11 in full. Cross-check every option against the official ordering table: 165855 = Cylinder Pressure Transducer; 11 = 0 to 6.8 bar (0 to 100 psia) pressure range with armor.
Q2. How can I distinguish a new unit from a used or refurbished one?
Inspect the label, connector, cable, mounting surfaces and packaging. New hardware should not show installation marks, repaired cable, contamination, refinished surfaces or inconsistent date and serial labels.
Q3. How should I verify that the supplier is legitimate and reliable?
Check the supplier legal entity, business address, domain-based email, bank beneficiary and traceable quotation. Require the quotation and invoice to state 165855-11 in full and identify the Bently Nevada 165855 Cylinder Pressure Transducer family.
Q4. Which technical details should an engineer confirm before purchase?
Confirm 0 to 100 psia range, armored execution, 7/8-14 UNF process connection, 18 to 30 VDC supply, 0 to 5500 Hz response and compatible O-ring material. Verify the connected monitor or signal-conditioning chain and the installation environment before replacement.
Q5. What physical evidence should be requested before payment?
Request time-stamped photos or video showing the full 165855-11 label, armored cable, sensor head, 1 m separation cable, electronics housing, process thread and supplied calibration data. Ask for close-ups that allow the ordering code and condition to be read without relying on a catalog image.
Q6. Can a similar suffix or related model replace 165855-11?
Not automatically. codes 12 through 17 change the pressure range; approval and O-ring selections must also be confirmed separately. A replacement requires documented mechanical, electrical, environmental and approval compatibility.
