ADM’s Range of Cost-Effective Pressure Switches
ADM stocks the TSA range of mechanical pressure switches. This new range of pressure switches is manufactured in the USA and has a proven track record for reliability and quality.
Explore our range of TSA range of mechanical pressure switches.
TSA Mechanical Pressure Switches
Low Pressure vs High Pressure: Selecting the Right TSA Series
The TSA range is split into two primary series designed for distinct operating pressures and fluid media:
TSA-APA: For Low-Pressure Applications
- Standard Pressure Ranges:
- 0.3 – 2.1bar measuring range
- 3.5 – 10bar measuring range
- Body Construction: Brass Body, ideal for corrosion resistance in pneumatic, water and low-pressure fluid systems.
TSA-BPA: For High-Pressure Applications
- Standard Pressure Ranges:
- 8.6 – 41bar measuring range
- 35 – 172bar measuring range
- 69 – 414bar measuring range
- Body Construction: Zinc-nickel-plated steel engineered for severe pressure spikes and harsh hydraulic environments.
Custom Configurations Available for Order
Other measuring ranges are available via special order, with the lead time being approximately 4 weeks.
Key Electrical & Mechanical Features
Each TSA model includes a Single Pole Double-Throw, also known as an SPDT, potential-free contact rated up to 250VAC / 5A.
The pressure switch contacts feature gold plating, allowing them to switch low-current signals reliably. For example, a control input to a PLC of less than 20mA; PLCs do not detect the switching if you use a standard silver contact.
Note: Once a high current is passed through the switch, the gold plating burns off, and it is no longer suitable for passing low currents.
Another key advantage of mechanical pressure switches is that they are passive devices, meaning they do not require their own power source, unlike pressure transducers.
Adjustability
TSA pressure switches can be custom-set to switch at a particular pressure. This is done either in the field or on the bench using a small Allen key (not included).
Standardised Industrial Connections
Process Connection: ¼" inch BSP standard thread, commonly found in industrial and mobile hydraulic equipment.
Electrical Connection: standard DIN 43650 plug for quick disconnect and reliable ingress protection.
Common Applications
The TSA series of pressure switches are the perfect cost-effective solution for a variety of industrial applications, including;
- Hydraulic Power Units: System overpressure relief and accumulator charge control.
- Pneumatic Automation: Cylinder position confirmation and pressure drop fail-safes.
- Industrial Pumping: Dry-run protection for high-volume positive displacement pumps.
- Heavy Mobile Machinery: Monitoring steering, braking and hydrostatic drive pressures.
