Surface mounted level controllers from Goldammer Series AM are engineered for external mounting on hydraulic fluid reservoirs. They feature clear acrylic or borosilicate glass sight tubes and adjustable magnetic contact cartridges for visual level monitoring and electrical signaling.

Side tank wall installation with center-to-center distances up to 2000 mm.
Visual sight tubes made of impact acrylic glass or durable Pyrex glass.
Infinitely adjustable reed switch contacts along the entire scale height.
Integrated bimetal dial thermometer indicating fluid temperature up to 100 °C.

Combined Level and Temperature Regulators Series NT

Goldammer Series NT combined level and temperature controllers integrate float level sensing and thermal regulation in a single compact assembly. Equipped with capillary thermostats or probe switches, they reduce the number of required tank penetrations on industrial power packs.

Dual monitoring of liquid level and temperature through a single opening.
Capillary thermostat with temperature adjustment span from 0 to 120 °C.
Up to four independent discrete level switching contacts per assembly.
Robust aluminum and polyamide connection terminal heads rated to IP65.

Electronic Water-in-Oil Detectors Series WM

Goldammer Series WM water indicators continuously detect free and emulsified water contamination in hydraulic and lubricating oils. Utilizing capacitive and conductive sensing methods, they protect high-pressure pumps and precision valves from cavitation and premature corrosive wear.

Detects moisture ingress in mineral, synthetic, and biodegradable oils.
Model WM 12 features a continuous 4–20 mA analogue output for PLC loops.
Model WM 1 incorporates alarm switching relays for immediate pump shutdown.
Available for 24 V DC industrial bus or 230 V AC electrical supply.

Level Regulators with Air Breather Filters Series BL

Goldammer Series BL units combine tank filling ports, air ventilation breather filters, and fluid level probes into a space-saving module. This configuration prevents ingress of airborne dust during dynamic fluid displacement and optimizes component density on top of power units.

Single tank mounting cutout for air breather filter and float level probe.
Replaceable air filter cartridges with micron ratings of 3, 10, or 25 um.
Filling strainer basket protects tank from coarse particulates during top-up.
Bistable reed contacts for dependable minimum and maximum level alarms.

Explosion-Proof Level Sensors DIN EN 60079-11

Intrinsically safe level regulators and sensors by Goldammer Series EX are engineered for operation in hazardous gas and combustible dust zones under ATEX directives and DIN EN 60079-11 (EExi). They serve chemical plants, industrial painting lines, and offshore turbine units.

Intrinsic safety classification conforming to EEx ia IIC standards.
Approved for dangerous gas zones 0, 1, 2 and combustible dust zones 20, 21, 22.
Seamless integration with galvanic isolating barriers and relays.
Robust corrosion-resistant grade 1.4571 stainless steel housings with IP67.

Operating Principles of Submersible Float Level Controllers Series IN

Submersible liquid level regulators by Goldammer Regelungstechnik Series IN operate using magnetically actuated reed contacts sealed within a corrosion-resistant brass or grade 1.4571 stainless steel guide tube.

A cylindrical or toroidal magnetic float moves vertically along the tube in direct response to fluid displacement inside the reservoir. When the liquid reaches predetermined switching thresholds, the magnetic field actuates the internal reed switch to open or close industrial control circuits.

This enclosed architecture isolates electrical components from working hydraulic oil and aggressive fluids, guaranteeing millions of trouble-free switching cycles without contact oxidation.

Mechanical Configuration of Surface-Mounted External Sight Gauges Series AM

For external fluid level verification on machine tanks where top cover penetration is impeded by hydraulic manifold blocks, Goldammer produces bypass level regulators Series AM.

The instrument fastens directly to the exterior tank wall via dual G 1/2 threaded union couplings or flanges, creating a communicating vessel arrangement.

The sight tube is fabricated from heavy-walled acrylic glass or thermal shock resistant Pyrex borosilicate glass, providing clear visual inspection.

Adjustable magnetic reed switch collars slide along the external tube profile, allowing maintenance crews to configure warning and emergency trip points without draining fluid from the tank.

Integrated RTD Platinum Sensors Pt100 and Capillary Thermostats Series NT

In modern high-performance hydraulic power units, continuous oil temperature supervision is just as critical as maintaining sufficient reserve volume. Combined regulators from Goldammer Series NT and TMA integrate float level detection and thermal regulation through a single mounting cutout.

The bottom or midsection of the guide tube incorporates a precision platinum resistance thermometer Pt100 compliant with DIN EN 60751 or an adjustable capillary thermostat.

This compact multi-function assembly enables automated PLC control loops to engage cooling heat exchangers at 55 °C and shut down pumps under critical overheating conditions.

Real-Time Water Ingress Detection in Hydraulic Oil Using Series WM

Ingress of moisture into hydraulic and lubricating circuits via cylinder seals or ambient condensation causes accelerated fluid oxidation, pump cavitation, and valve spool corrosion.

Electronic water sensors by Goldammer Series WM continuously track dissolved and free moisture saturation within oil reservoirs.

Model WM 12 delivers an analog 4-20 mA current loop transmission to PLC controllers, while model WM 1 features an onboard electromechanical relay output to immediately decouple hydraulic drive motors prior to harmful emulsion formation.

Intrinsically Safe Explosion-Proof Engineering Compliant with DIN EN 60079-11

For chemical processing facilities, offshore oil and gas platforms, and automated painting booths where hydraulic power packs operate in combustible atmospheres, Goldammer supplies explosion-proof Series EX instruments.

The sensors conform to European ATEX directives for intrinsic safety category EEx ia IIC.

Internal capacitance and inductance values are strictly minimized, permitting reliable connection through standardized Zener safety barriers or galvanic isolating amplifiers in hazardous gas zones 0, 1, 2 and combustible dust zones 20, 21, 22.

Engineering Selection Guidelines and Preventative Maintenance Procedures

When specifying Goldammer Regelungstechnik instrumentation for plant upgrades or retrofit installations, engineering personnel must evaluate reservoir depth, mounting thread standards, kinematic fluid viscosity, and temperature extremes.

Accurate part number verification is accomplished using the factory rating plate affixed to the device body or tank fabrication drawings.

Routine preventative maintenance involves inspecting float travel along the guide stem, cleaning the breather filter element on Series BL modules, and verifying electrical contact loop resistance during scheduled plant turnarounds.
