Weksler AS5 and AS6 Industrial Air Duct Thermometers
Weksler AS5 and AS6 series air duct thermometers measure air and gas temperatures within ventilation and conditioning ducts. Units incorporate a reversible mounting flange for easy duct wall installation. Extended thermal stems reach up to 24 inches to measure core airstream conditions accurately.
- Reversible duct mounting flange provides secure installation on sheet metal walls
- Extended thermal stem lengths ranging from 6 to 24 inches for deep duct penetration
- High-contrast dial graduations facilitate accurate readings during inspection walks
- Perforated stem extension sleeve allows free laminar air circulation around sensor
Weksler Heavy-Duty Process Thermowells
Weksler thermowells protect temperature sensors against high line pressures, abrasive velocity, and aggressive chemical fluids. Precision-machined from brass and stainless alloys, these wells enable thermometer replacement without draining or shutting down running process lines.
- Solid-machined bar stock construction in brass and 304/316 stainless for high pressure
- Standard threaded NPT, socket-weld, and flanged connections for process installations
- Precision bore diameter tailored to industrial glass and bimetal thermometer stems
- Optimized heat transfer geometry minimizing thermal lag and response response latency
Weksler EA14 Series and Industrial Pressure Gauges
Weksler EA14 contractor gauges provide reliable pressure readings in mechanical HVAC, plumbing, and boiler systems. Equipped with bronze or stainless Bourdon tubes, these instruments deliver dependable accuracy. Liquid-filled models are available to suppress intense pulsation and system chatter.
- Rugged 4.5-inch coated steel case engineered for commercial mechanical equipment rooms
- Phosphor bronze or 316 stainless Bourdon tube mechanism paired with precision gearing
- Full scale accuracy conforming to ASME B40.100 standards for mechanical contractors
- Optional liquid fill fluid damping pressure spikes and pump line mechanical vibrations
WGTC Cirrus Wireless Temperature Monitoring System

- Long-range LoRa wireless protocol ensuring reliable penetration across plant floors
- Central gateway connects up to 60 distributed thermometers into a single network node
- Direct AWS cloud synchronization paired with mobile dashboard for setting threshold alarms
- Extended battery life powering sensor transmitters for multi-year unattended operation
Installation and alignment routines for Weksler Adjust-Angle thermometers
Weksler Adjust-Angle industrial glass thermometers mount into mechanical piping, vessels, and heat exchangers using compatible protective thermowells.
The articulated joint design allows operators to rotate the display scale 360 degrees around the stem axis and adjust the viewing angle across 180 degrees for optimal line-of-sight readability.
During scheduled mounting, the swivel hex nut is tightened to specified torque ratings without imparting torsional strain to the glass capillary tube assembly. The thermowell cavity is charged with thermal conductive paste to minimize measurement latency.
Technicians inspect the blue spirit indicator column to ensure continuous, bubble-free fluid separation.
Calibration and verification procedures for Weksler 3AA and 5AA bimetals
Periodic accuracy verification and calibration for Weksler 3AA and 5AA bimetal thermometers is performed using stirred comparison liquid baths or dry-block thermal calibrators.
Calibration runs sample at least three cardinal setpoints distributed across the operating span once thermal equilibrium has stabilized.
When scale deviation is observed, operators adjust calibration using an external reset screw located on the rear face of the hermetic 304 stainless enclosure. Turning the screw with a precision hex driver repositions the pointer relative to reference standards.
Following adjustment, units undergo thermal cycling at scale limits to confirm zero repeatability.
Mounting guidelines for Weksler AS5 and AS6 air duct thermometers
Installing Weksler AS5 and AS6 thermometers on ventilation ducts and air handling plenums utilizes an integrated reversible sheet metal flange. The flange fastens to duct exterior sheet metal using self-tapping screws, establishing a rigid, vibration-resistant mount for the extended sensing stem.
Stem insertion depth is selected to position the perforated protective sleeve in the high-velocity core of the airstream, at least one-third of the hydraulic duct diameter away from interior walls. Upstream disturbances such as dampers and filtration frames must be bypassed.
Scale faces are positioned parallel to inspection walkways for clear operator monitoring.
Thermowell wear inspection and vortex-shedding resonance management
When operating Weksler thermowells in high-velocity steam, gas, or liquid process headers, routine inspection for mechanical erosion and surface pitting is essential.
Scheduled maintenance protocols incorporate ultrasonic wall thickness testing alongside liquid penetrant inspection across threaded and flanged process connections.
Thermowell dimensions must be verified against wake frequency calculations defined in ASME PTC 19.3 TW standards to prevent resonance-induced fatigue failure. Any component displaying cavitation grooving or wall thinning is slated for scheduled replacement.
Thermometer replacement proceeds from the dry well interior without reducing line operating pressure.
Inspection procedures for Weksler EA14 gauges and liquid fill levels
Maintenance for Weksler EA14 series contractor and process gauges includes verifying Bourdon tube weld integrity, inspecting movement gear backlash, and monitoring liquid fill clarity.
If fluid loss occurs, damping glycerin is replenished through the elastomeric fill plug, removing air pockets to dampen mechanical line pulsation effectively.
Gauge calibration checks are conducted on hydraulic deadweight testers across five rising and falling pressure increments.
Dial faces showing cracked crystal lenses or pointer zero-shift beyond published ASME B40.100 tolerances receive new internal subassemblies and replacement seals prior to operational sign-off.
Network telemetry diagnostics for WGTC Cirrus wireless sensors
Preventative service for WGTC Cirrus wireless temperature monitoring hardware encompasses verifying internal lithium battery cell voltages, testing LoRa RF transmission packet strength at the central gateway, and testing analog-to-digital converter linearity across sensor channels.
The AWS cloud dashboard is reviewed to adjust high and low temperature alert thresholds and examine historical trend logs. Firmware updates are rolled out systematically to optimize power consumption profiles and ensure continuous end-to-end data transmission across industrial mechanical spaces.
