If gases escape through leaks ultrasonic noises are generated. By means of the LD 300 leakages can be detected in the ultrasonic range even from distances of several meters. LD 300 transforms the inaudible signals into a frequency which can be identified by means of the provided sound-proof headset. In depressurized systems an ultrasonic tone generator can be used of which the signal travels through smallest openings.

If there is no measuring site with 1/2″ ball valve present it can be set up by means of spot drilling collars.
The spot drilling collar is imposed onto the pipe and tightened via thread rods. The enveloping rubber gasket is pressure-tight up to 10 bar. By means of the drilling jig it is possible to drill through the 1/2″ ball valve into the existing pipe.

The entry of the correct inner diameter is essential for an accurate consumption measurement.

Digital Pressure Gage with 0.5% Accuracy

Selectable Engineering Units, Comes Standard with Rubber Boot

The Series DPGWB/DPGAB pressure gages offer 0.5% full scale accuracy in a rugged, easy-to-use unit at prices comparable to mechanical gages. The DPGWB stainless steel wetted material makes it suitable for a wide variety of liquids or gases. The gages feature user-selectable units of measure allowing one gage to be used for a variety of pressure scales. The DPGWB/DPGAB come with a protective rubber boot to protect against short drops and rough handling.

• Ideal for checking line pressures at system startup.

Mini Digital Pressure Controller

Small, Lightweight, 6 Selectable Pressure Units

The Series MDPC is a slim, gas pressure sensor that is small in size and light in weight. This pressure controller supports many installation methods and features high measurement accuracy. This small controller yields excellent stability, high shock and vibration resistance. The MDPC also provides good over-load capacity and heat resistance. It can be utilized in many industries such as: high-tech electronics, general processing, food packaging and automatic assembly. The MDPC features 6 user selectable pressure units and a large, LED 3-color display with selectable color options that allow for easy reading.

Subminiature Pressure Switch

Field Adjustable, Submersible Models

Designed for OEM applications, the Series A2 is economical and is equipped with high proof pressure capabilities for demanding applications. The A2 is available with either spade terminals or flying leads (submersible). Switches with spade terminals can be easily adjusted in the field.

Adjustable Pressure Switch

Vacuum and Pressure Ranges, 5A Switch, Compact Size

Miniature Series APS/AVS Adjustable Switches offer reliable switching for pressure/vacuum alarm, shutdown or control. The units are readily adjustable throughout their range using the locking adjusting ring and indicating pointer. The body is constructed of stainless steel for durability in harsh environments. Switches include 12″ (30 cm) wire leads sealed with epoxy for additional protection.

Bourdon Tube Pressure Switch

Pressure Ranges to 8000 psi (551.6 bar)

Customers tell us that this is the best pressure switch made. The Mercoid D Series is one of the world’s broadest lines of pressure switches. Whatever your application might be, it is most probable it can be fully satisfied with a D Series pressure switch.

Dual-Action Explosion-Proof Pressure Switch

Explosion-proof and Weatherproof Housing

Explosion-proof, UL & CSA Listed for Class I, Groups B, C & D and Class II, Groups E, F & G. The H2 is designed for sequencing two different actions as pressure of a liquid or gas increases or decreases. The design consists of two concentric pistons operated by a single diaphragm with one pressure chamber. Each piston actuates a separate switch independent of the other. The switches may be adjusted to operate together, at opposite ends of the range or at two intermediate set points. The threaded top is removed to field adjust or service switches without disturbing electrical or pressure connections. The Duotect® switch is explosion-proof and weatherproof. It can be mounted in any position and is not affected by vibration.

Diaphragm Operated Pressure Switch

Visible Setpoint, Adjustable Deadband, Hermetically Sealed Snap Switch, Weatherproof and Explosion-proof

Weatherproof and Explosion-Proof in One Economical Enclosure

Extremely rugged construction assures excellent reliability in chemical, petroleum and industrial plants. New design also provides burst pressure protection to 3000 psi (206 bar). The rolling diaphragm design maintains a constant effective area to minimize friction. This results in a minimum deadband as low as 5% of full scale. Since many applications require higher deadbands, the SA1100 includes a separate adjustment of this when necessary. A pump being used to control liquid level in a tank would be a typical situation where this feature would be important. Both setpoint and deadband adjustments are protected, yet clearly visible behind a clear polycarbonate window and are fully isolated from the electrical components for additional safety. A 7/16″ open-end wrench is the only tool required to change settings. Terminal blocks are provided for switch wiring connections and both internal and external ground screws are included. Standard housing is weatherproof to NEMA standards 1 through 4X and 13; explosion-proof to NEMA 7, Class I, Groups B, C & D; NEMA 9, Class II, Groups E, F & G. Optional construction adds drain to meet NEMA 3R IP54.

• Chemical, petroleum, food and drug processing industries. Used indoor, outdoor or in explosion-proof area.
