Custom Products

PMC prides itself on solving application challenges with custom designs based on our sensor technology. Below we show a selection of these. If you have a special requirement for pressure, level and other measurands please send us the details and we will try to provide you with a solution.


Environmental Safety Warning System

Environmental Safety Warning System

Therm-Alert is a very flexible and customizable sensing and alarm system intended to warm employees and management when temperature or dew point in working areas reach dangerous levels.

Low Pressure Differential Pressure Transmitter

Low Pressure Differential Pressure Transmitter

The PMC Low Pressure, Differential Pressure Transmitter is designed to measure pressure across filter elements. Utilizing the PMC flush-mount diaphragm on the positive pressure side and a 1/8" NPT nipple for the reference pressure side. It is well suited for measuring pressure drop across a line of filter elements. To prevent contamination of the capacitive pressure element, no liquids may enter the low pressure side.

Miniature Depth / Level Transmitter

Miniature Depth / Level Transmitter

The MTM 3000 Miniature depth and level pressure sensor is available for applications where space is very limited. The housing diameter of 0.39 inches offers the user an ideal high performance level measurement in small diameter, i.e. 1/2" monitoring wells, stand pipes and bore holes. The Titanium construction and integral polyurethane cable provide a reliable long term solution for these difficult-to-measure applications. Kevlar is used as a cable reinforcement to avoid any elongation, particularly when long lengths of cable are required for deep wells. Long term stability of typically ±0.1% per year also contributes toward a maintenance-free installation. 

High Pressure Transducer

High Pressure Transducer

The VB series has been designed specifically for those applications where very high pressures up to 45,000 psi are to be measured, and temperatures might be as high as 500°F. Typical applications range from oil field instrumentation, including MWD down hole, to turbine engine monitoring. The performance is achieved by using the very latest processes in thin film stain gauge techniques and is offered without active amplification or compensation.

Moisture Barrier Breather Vent

Moisture Barrier Breather Vent

This small fitting provides a moisture barrier and ventilation for devices requiring atmospheric pressure. PMC developed this high-quality component as a solution for their instrumentation housings. Over a short period of time, this vent has established itself as an excellent off-the-shelf product. Current customers include major instrumentation companies, GPS system and junction box manufacturers. This unique item is continually finding a real need for users in many industrial applications and can be designed to meet individual needs and specifications.

DS Level Probe

DS Level Probe

The model DS series (Dip Stick Level Probe) transmitter is designed for top mount locations in tanks. This unit is ideal for installation in mixing, blending, white water tanks and wastewater treatment locations. Supplied with either a 1" (Miniature) or 1 1/2" ceramic diaphragm sensor the Dip Stick Level Probe transmitter provides a stable measuring environment for many difficult applications. Non-standard lengths can be order to individual specifications.

Mud Level and Density Monitor LD Series

Mud Level and Density Monitor LD Series

PMC specializes in reliable precision transmitters for fluid level measurement in challenging locations and applications since 1963. This compact, rugged transmitter combines two ceramic capacitive sensors to accurately measure drilling fluid density and level. Designed for simple installation into the Mud Pit, the 7.5 feet long dual sensor assembly can be extended or mounted into the side of the tank (pit).

Fluid Level Alert for Safety and Control

Fluid Level Alert for Safety and Control

The PMC Lev-ALERT can provide visual or audio warnings when the fluid/water/sewage reach dangerous levels. It also provides switch outputs to control appropriate output pumps or input valves.
