Thermocouple Limit Alarm suits food service equipment.

May 12, 2014

To let operator know of potentially dangerous conditions, Series TSF-DF provides visual alarm and 16 A SPST relay output when process has reached high temperature limit. Once temperature has returned to normal, non-alarm condition, unit can reset automatically or be manually reset by user. Buttons on face of control can only be used to reset alarm condition, preventing user from tampering with settings. All programming is done through master control and program configuration key.

Pneumatic Torque Limiters provide overload protection.

October 5, 2009

Using ball/detent interface and proximity sensor, single-position TL Series immediately disengages machine shaft when excessive torque or machine jam occurs, protecting downstream equipment and product from damage. By utilizing pneumatic actuation, units facilitate remote trip-out torque adjustment via air regulator, allowing overload protection while machine is in use. Limiters are available in both semi-open and totally enclosed nickel-plated models. Read More

Axial Piston Pumps offer torque limiting option.

March 3, 2009

Designed for open circuit mobile equipment and industrial applications, P1/PD Variable Displacement Pumps are rated for continuous operation at 2,600 rpm and pressures to 4,060 psi. Torque limiter adjusts flow in circuit to keep prime mover from stalling under heavy loads. Available in 5 configurations, single spring unit monitors pressure and displacement as measured by pump's hanger angle. As pressure rises, flow is reduced according to zero adjustment spring rate.
