Capacitance Probes
Quality probes made in the USA

BinMaster capacitance probes are designed with features that make them accurate and reliable, even under rigorous or harsh conditions.

All models of PROCAP capacitance probes are made in the USA and are simple to use, offer long-lasting durability, and are maintenance free.

Probes for every process

Standard Probes

The standard PROCAP I & II probes are offered with an expansive choice of Delrin, Teflon, stainless steel and bare probes—all custom assembled to a customer’s specification.

Hazardous Locations

PROCAP IX & IIX probes are designed for use in hazardous locations for Class I, Groups C & D and Class II, Groups E, F & G using either a standard or flush mounted sensing probe.

Sanitary Applications

Food and pharmaceutical plants find PROCAP 3A sanitary probes with a thread-free mounting flange and clean-in-place, tri-clamp connection ideal for 3-A, USDA, or food grade use.

Bendable Probes

A bendable probe can be used to avoid obstructions in a vessel and is a clever solution for use in smaller mixers, hoppers, or containers.

Heavy Duty

Heavy duty HD probes are made of 1” solid stainless-steel for use in high temperatures up to 500°F. Popular in power plants, they can be used in heavy or challenging materials such as coal, fly ash, or clinker.

Flush Mounted

Flush mounted PROCAP FL probes are nonintrusive and ideal for use on a vessel wall, conveyor housing, chute, or tight spaces where material may damage a standard probe.

Remote Electronics

For hostile areas with high temperatures or vibration, the PRO Remote has remote electronics to distance the electronics up to 75 feet from the sensing probe.

Automatic Calibration

For fast installation, the PRO AUTO-CAL probes with automatic calibration set up in seconds using a magnet without opening the unit cover.

Compact and Mini Probes

Compact Probes

COMPACT PRO probes are ideal for smaller vessels and tight spaces such as chutes, conveyors, pipes, or small hoppers.

Mini for Liquids

Great for food or pharmaceuticals, the MCP-100 mini capacitance probe is a compact sensor for level measurement and pressure detection for water-based liquids in sanitary and hygienic applications.

Mini for Solids

The MCP-200 point level detector is used in tanks, vessels, hoppers, or feeders containing bulk solids. There’s hygienic options for food and pharmaceutical processing.

Extended Mini

The MCP-300 is an extended mini capacitance probe with a stainless-steel tube customized in lengths from 2.5” to 9.8”. Use it for point level indication in foodstuffs, dairy cultures, or breweries, and in the pump room to detect leaks.

How PROCAP Works

PROCAP capacitance probes measure the difference in the dielectric constant of the material versus the surrounding air allowing the sensor to detect the presence or absence of material. The probes are very responsive, sensing changes in capacitance as small as just one picofarad.

Capacitance probes are often wired to a light, horn, or point level alarm panel for alert status indication

Mounting Options

Mount BinMaster’s PROCAP capacitance probes on the top, side, or cone of the vessel for high, mid, or low-level detection.

Capacitance Probe LED Light

Sensor Status Notification

An LED light on top of the unit indicates the sensor status is covered, uncovered, or in a failed condition. This provides fall-safe protection and prevents process mishaps caused by a power failure.

ProShield Fights Bridging & Buildup

Pro-Shield protects against false readings due to buildup on the probe or bridging between the sidewall and the probe. This allows the probe to be used in dusty, sticky, or clingy materials.

Simple Quick Set Calibration

Calibration of PROCAP sensors is fast and precise. Using two single-turn potentiometers allows for sensitivity setting even when no material is present.

Time delays prevent false alarms

Users simply set a time delay of up to 30 seconds before the sensor alerts to a signal change. The time delay feature minimizes false signals caused by sudden material shifts or splashing liquids.

Unaffected by RF Interference

PROCAP probes are immune to RF signals from electronic plant equipment or two-way radios. This ensures interference-free operation and prevents disruptions to processing operations.

Made to Order

BinMaster builds each PROCAP probe to a customer’s specification. Each sensor is specified a power pac, fitting, lag, probe, length, and mounting plate best for its material, vessel, and operating environment. Each sensor is made in just days in BinMaster’s factory in Lincoln, Nebraska.

Vast Probe Selection
