Contact closure alarms

TetraScience is excited to announce our latest monitoring capability—Contact Closure.

What is it?

A sensor which detects changes in voltage (usually zero/nonzero).

Why is it important?

Many alarms are set off by a circuit break or a connection which causes the voltage to go from zero to a nonzero value or vice versa. By adding our sensor to the circuit, we can stream the voltage value and alert you as soon as there is a change.

A few use cases

Several instruments including storage units and manifolds have built-in audible alerts to if the liquid nitrogen level is low or if they are left open. If no one is in the lab to hear the alert, they are not helpful. By deploying a contact closure alarm with TetraScience, users receive notifications that the unit was placed in alert mode. With additional context by monitoring temperature, humidity, and CO2 with TetraScience Monitoring, users quickly get an understanding of exactly how dire the situation is.


Contact closure on a CO2 manifold.

For “non-standard” units, like a nitrogen manifold or wastewater tank, contact closure can be a useful tool. For example, above we have a picture of contact closure deployed on a CO2 manifold. This particular company uses CO2 across all of its incubators and biosafety cabinets. With contact closure, its Ops team are made aware if CO2 levels are lower than expected, from within in the lab or from their couch at home.
