This transducer provides repeatable, precise depth measurements under the most adverse conditions\. \\It has been designed for installation in Class 1, Division 1, Groups A,B,C and D; Class II, Division 1, Groups E,F and G; Class III, Division 1 hazardous locations, when connected to the appropriate Stahl apparatus\. \\The Model 456\-15 features high performance internal signal conditioning\. An isolated diaphragm sensor has been incorporated for use with hostile fluids and gases\. This sensor uses a silicon pressure cell that is fitted into a stainless steel housing with an integral, compliant stainless steel barrier diaphragm\. The sensor assembly is housed in a rugged, compact 316 SS case, which provides for a variety of pressure inputs as well as electrical output connections\. This item is no longer sold by Time Mark \(though it is still in production with the original manufacturer\.\) - [60\-120V](https://time-mark.com/product/60-120v/): The Model 60 is a Bistable Impulse Latch Relay\. When power pulse is applied, the Impulse LED on the top of the relay will illuminate and the relay will change state\. Power can then be removed and the relay will remain in that state \(mechanical latch\)\. When power pulse is reapplied, the relay will change state and latch\. - [60\-240V](https://time-mark.com/product/60-240v/): The Model 60 is a Bistable Impulse Latch Relay\. When power pulse is applied, the Impulse LED on the top of the relay will illuminate and the relay will change state\. Power can then be removed and the relay will remain in that state \(mechanical latch\)\. When power pulse is reapplied, the relay will change state and latch\. - [60\-24V](https://time-mark.com/product/60-24v/): The Model 60 is a Bistable Impulse Latch Relay\. When power pulse is applied, the Impulse LED on the top of the relay will illuminate and the relay will change state\. Power can then be removed and the relay will remain in that state \(mechanical latch\)\. When power pulse is reapplied, the relay will change state and latch\. - [24](https://time-mark.com/product/24/): The Model 24 is a microcontroller\-based universal 3\-phase monitor for protecting 3\-phase motors from abnormal power conditions\. It can detect under voltage, over voltage, voltage unbalance, reverse phase, and single\-phasing even when regenerated voltage is present\. The Model 24 includes adjustable trip and restart delays to prevent nuisance tripping during power fluctuations and short cycling in compressor applications\. The LED status indicators and adjustment pots for Voltage Adjustment, % Unbalance, Restart Delay and Trip Delay are mounted on the front of the unit for easy access\. Automatic or manual restart versions are available\. The Model 24 does not require a neutral connection and can be used on either Wye or Delta systems\. All versions of the Model 24 are available with optional gold flashed silver contacts for low current applications\. ## Categories - [Web Features](https://time-mark.com/blog/category/web-features/) ## Product categories -
